Palestinian officials said three Hamas training camps and one belonging to a smaller group had been struck.
Hamas’s military wing, the Izzedine al-Qassam Brigades, claimed that it had used anti-aircraft missiles against Israeli jets flying over the coastal territory.
On Saturday two Palestinian teenagers were also killed by Israeli tank fire east of Rafah.
The pair were in a group approaching the border in “a suspicious manner”, Israel’s army said.
It came after four Israel Defense Forces (IDF) soldiers were injured, two seriously, in an explosion on Saturday afternoon east of the town of Khan Younis.
The army said the explosive device had been planted during a demonstration there on Friday and was attached to a flag which the troops attempted to remove.
Israeli Prime Minister Benjamin Netanyahu, who is attending a security conference in Munich, Germany, said: “The incident on the Gaza border is very serious. We will respond appropriately.”

Israeli media also said a rocket from Gaza fell near a house in the south of the country on Saturday evening. There were no casualties.
Israel holds Hamas responsible for all rocket and mortar fire from the territory. Hamas has fought three wars with Israel since 2008.
Correspondents say the border area has been generally quiet in the last few years but there has been an increase in violence since US President Donald Trump’s announcement in December recognising Jerusalem as Israel’s capital.
Israel regards Jerusalem as its indivisible capital. Palestinians want the east of the city, which Israel occupied in the 1967 Middle East war, to be a capital of a future state.

President Donald Trump has rebuked the FBI for missing signals before Wednesday’s school shooting in Florida.
The agency was “spending too much time trying to prove Russian collusion with the Trump campaign”, Mr Trump tweeted.
“There is no collusion. Get back to the basics and make us all proud.”
The FBI has admitted it failed to act on a tip-off about suspected shooter Nikolas Cruz, who has confessed to the shooting at a high school in Parkland in which 17 people died.
It was the deadliest US school shooting since 2012 and has re-ignited long-running debates about tougher firearm restrictions.
Earlier, students who survived the shooting rallied in Florida, demanding tighter legislation on gun control and criticising the president for receiving financial support from the National Rifle Association (NRA) during his presidential campaign.
What was President Trump referring to?
In his tweet, he wrote: “Very sad that the FBI missed all of the many signals sent out by the Florida school shooter. This is not acceptable.”
He appeared to link the agency’s failures in the specific case to the time it has spent investigating possible collusion between Russia and the Trump team during the 2016 presidential campaign.
Earlier this week, 13 Russians were charged with interfering in the US election, in a major development in an FBI investigation now led by Special Counsel Robert Mueller.
Three Russian companies were also named in the indictment.
Russian Foreign Minister Sergei Lavrov on Saturday dismissed the charges as “blather”, saying he would not comment further until he saw “facts”.
What mistakes did the FBI admit to?
It said it did not properly follow up on a tip-off about Mr Cruz last month when a person close to the suspect contacted the agency to provide “information about Cruz’s gun ownership, desire to kill people, erratic behaviour, and disturbing social media posts, as well as the potential of him conducting a school shooting”.
The 5 January tip was not the only information the FBI received.
In September, a Mississippi man reported to the law enforcement agency a disturbing comment left on a YouTube video under Mr Cruz’s name.
Mr Cruz, 19, was also reportedly investigated by local police and the Department of Children and Family Services in 2016 after posting evidence of self-harm on the Snapchat app, according to US media reports.
Child services said he had planned to buy a gun, but authorities determined he was already receiving adequate support, the reports say.
What happened at Saturday’s rally in Florida?
Students and their parents – as well as politicians – took part in the event in Fort Lauderdale, close to Parkland. Thousands of people attended, according to the Associated Press.
According to the Center for Responsive Politics, the NRA spent $11.4m (£8.1m) supporting Mr Trump in the 2016 campaign, and $19.7m opposing Hillary Clinton.

Ryan Deitsch, who was among those hiding in a school toilet during the attack, urged lawmakers to pass more restrictive measures on gun ownership.
“The least lawmakers can do is vote on something. What’s the worst that can happen?” the 18-year-old said.
In another development, a prominent Republican donor is threatening to withhold funding from candidates who fail to endorse legislation against assault weapons.
Al Hoffman Jr, a Florida real estate developer, announced the move in an email to several Republican leaders, including the state’s governor, Rick Scott, according to the New York Times.

Israeli PM Benjamin Netanyahu has sharply rebuked his Polish counterpart for saying that Jews were among the perpetrators of the Holocaust.
He said the remarks by Mateusz Morawiecki at the Munich Security Conference were “outrageous”.
Mr Netanyahu said they showed “an inability to understand history”.
The dispute comes weeks after Israel condemned a new Polish law making it illegal to accuse the Polish nation or state of complicity in Nazi crimes.
The legislation was signed into law by President Andrzej Duda but also referred to the country’s highest court to consider its constitutionality.
What did Mr Morawiecki say in Munich?
He was responding to an Israeli journalist who asked if anyone who said there were Polish collaborators in the Holocaust would be considered a criminal in Poland under the new law.
Mr Morawiecki said: “It’s extremely important to first understand that, of course, it’s not going to be punishable, not going to be seen as criminal to say that there were Polish perpetrators – as there were Jewish perpetrators, as there were Russian perpetrators, as there were Ukrainian…. not only German perpetrators.”
Mr Morawiecki has not publicly responded to Mr Netanyahu’s criticism.
What does the new Polish law state?
It says that “whoever accuses, publicly and against the facts, the Polish nation, or the Polish state, of being responsible or complicit in the Nazi crimes committed by the Third German Reich… shall be subject to a fine or a penalty of imprisonment of up to three years”.
But it adds the caveat that a person “is not committing a crime if he or she commits such an act as part of artistic or scientific activities”.
The country has long objected to the use of phrases like “Polish death camps”, which suggest the Polish state in some way shared responsibility for camps such as Auschwitz. The camps were built and operated by Nazi Germany after it invaded Poland in 1939.
But the more contentious point raised by the law is whether it will outlaw references to acts of individual complicity by Poles with the Nazis – something historians say there is clear evidence for.
How did Israel respond?
The Israelis have been furious about the legislation, which Mr Netanyahu has described as an attempt to rewrite history and deny the Holocaust.
Deputies from across Israel’s often fractious political spectrum have united to denounce it.
Following the passage of the law in the Senate, Israel’s Foreign Ministry asked to postpone the visit of a senior Polish official.
Now, Israeli MPs are backing a bill that would expand Israel’s existing Holocaust denial laws to include a five-year jail sentence for anyone denying or minimising the role of Nazi collaborators, including Poles, in crimes committed in the Holocaust.
The amended law would also give legal aid to any Holocaust survivor telling their story who is prosecuted in a foreign country.
Poland was attacked and occupied by Nazi Germany. Millions of its citizens were killed, including three million Polish Jews in the Holocaust.
Six million Jews were killed in the Holocaust overall.
More Poles have been honoured by Israel for saving the lives of Jews during the war than any other nation.
However, historians say others were complicit by acts such as informing on Jews in hiding for rewards, and participating in Nazi-instigated massacres including in Jedwabne where hundreds of Jews were murdered by their neighbours.
Media captionMr Netanyahu said Iran was falsely denying that it sent a drone into Israeli territory last week
Israel’s prime minister has launched a stinging attack on Iran, telling a security conference in Munich it is the “greatest threat to our world”.
Benjamin Netanyahu said Israel would “not allow Iran’s regime to put a noose of terror around our neck”.
Mr Netanyahu drew a parallel between the 1938 Munich Agreement, seen as a failed attempt to appease Nazi Germany, and the 2015 Iran nuclear deal.
He said the deal had only “unleashed a dangerous Iranian tiger”.
“We will act without hesitation to defend ourselves and we will act if necessary,” he said, “not just against Iran’s proxies that are attacking us but against Iran itself”.
Mr Netanyahu accused Iran’s foreign minister and representative in Munich, Mohammad Javad Zarif, who is due to address delegates later on Sunday, of being the “smooth-talking mouthpiece of Iran’s regime… [who] lies with eloquence”.
He said Iran was falsely denying that it sent a drone into Israeli territory last week which was shot down by Israeli forces.
Holding up a remnant of what he said was the destroyed drone, he addressed Mr Zarif directly: “Do you recognise this? You should, it’s yours. You can take back a message to the tyrants of Tehran: Do not test Israel’s resolve.”
OP’S NEWS diplomatic correspondent Jonathan Marcus, at the conference, says this theatricality was vintage Benjamin Netanyahu, from a prime minister embattled at home with potential corruption charges looming over his head.
The former US Secretary of State John Kerry later insisted that Mr Netanyahu’s assertion that Iran would be on its way to a nuclear bomb within a decade was “fundamentally not accurate”.
Why the recent spike in tensions?
The immediate trigger is last week’s confrontation – the first known direct engagement between the Israeli and Iranian militaries.
Israel launched raids against Iranian targets in Syria after saying it had intercepted an Iranian drone crossing the Syria-Israel border.
Image copyrightEPAImage captionIsrael lost a fighter jet for the first time in more than a decade
During the offensive, an Israeli F-16 fighter jet was shot down by Syrian air defences, its pilots ejecting in northern Israel.
It was believed to be the first time Israel had lost a jet in combat since 2006.
After the attack, Mr Netanyahu said Iran had “brazenly violated Israel’s sovereignty” and vowed that Israel would defend itself.
What about in the longer term?
The rivalry between Iran and Israel has been exacerbated in recent years by the regional instability – from the toppling of Saddam Hussein’s regime in Iraq, which removed a counterweight to Iranian regional power, to the ongoing proxy war being fought between many different powers in Syria.
Israel is a vocal opponent of the 2015 deal struck between Iran and six world powers which lifted crippling sanctions in exchange for curbs on Iran’s nuclear programme.
Mr Netanyahu will be followed on to the stage in Munich by Iran’s Foreign Minister Zarif and it is a moot point who will be the more welcome guest, says the BBC’s Jonathan Marcus.
While there is strong support in Europe for the nuclear deal with Iran, there is a growing sense in several capitals that more must be done to curb Iran’s destabilising regional role.
It has emerged as one of the great victors from the chaos in Syria.
He is likely to direct his Munich appearance as much at his domestic audience as to the wider international community, our correspondent says, insisting that he remains the essential leader for Israel at a time of growing regional competition.
Tibetan writer Tsering Woeser told AFP she was “very worried” about the state of the monastery.
“Tibetans consider Lhasa to be a sacred place, but Jokhang is a sacred place within that sacred place – the most sacred in all of Tibet,” she said.
“Some people say it’s only because of Jokhang that the holy city of Lhasa exists at all.”
“No matter where they are in the world, Tibetans all wish to come to Lhasa to pray at Jokhang; it’s the wish of a lifetime. Many who make pilgrimage to Lhasa prostrating do so just to visit the temple,” she added.
The fire comes as Tibetans celebrate Losar, their traditional new year, which began on Friday.

Tibet has had a tumultuous history, during which it has spent some periods functioning as an independent entity and others ruled by powerful Chinese and Mongolian dynasties.
China sent in thousands of troops to enforce its claim on the region in 1950. Some areas became the Tibetan Autonomous Region and others were incorporated into neighbouring Chinese provinces.
China says Tibet has developed considerably under its rule.
But rights groups say China continues to violate human rights, accusing it of political and religious repression – something Beijing denies.

Sixty-six people are feared to have been killed in a passenger plane crash in the Zagros mountains in Iran.
The Aseman Airlines plane, en route from Tehran to the south-western city of Yasuj, came down near the city of Semirom in Isfahan province.
The Red Crescent deployed search and rescue teams to the site. The airline has retracted a statement saying definitively that all aboard were dead.
Flight EP3704 left Tehran at 04:30 GMT, and crashed about an hour later.
The aircraft, a twin-engine turboprop, came down on Dena Mountain, 22km (14 miles) from Yasuj, news channel Irinn reported.
Sixty passengers, two security guards, two flight attendants and the pilot and co-pilot were on board.
The airline initially said everyone had been killed, but said later: “Given the special circumstances of the region, we still have no access to the spot of the crash and therefore we cannot accurately and definitely confirm the death of all passengers of this plane.”
Bad weather has hampered rescue efforts. Emergency teams have had to travel to the crash site by land rather than using a helicopter.

Iran has suffered several aviation accidents in recent years and has an ageing aircraft fleet.
The country has struggled to obtain spare parts to maintain its planes in the face of international sanctions imposed to curb its nuclear programme.
Those sanctions have been mostly lifted under a 2015 deal between Iran and the US alongside several other powers.
Aseman, Iran’s third largest airline, signed a contract with Boeing last year to buy 30 of its latest medium-range 737s.
The crashed plane, a French-Italian-made ATR 72-500, was 25 years old, Iran’s civil aviation organisation said.
Iran’s Supreme Leader, Ayatollah Ali Khamenei, expressed “deep sympathy” for relatives of those on board, saying the accident “saddened the hearts”.
Image copyrightDEPARTMENT OF VETERAN AFFAIRSImage captionVivieca Wright Simpson had worked with Secretary Shulkin for the past two years
The chief of staff for Veterans Affairs Secretary David Shulkin retired on Friday amid accusations that she doctored emails, media reports say.
The agency’s inspector general accused Vivieca Wright Simpson of writing false emails so that air fares to Europe for the secretary’s wife would be paid for with public money.
Ms Wright Simpson allegedly got tickets worth $4,300 (£3,100) covered.
She has disputed the allegations, according to the New York Times.
Ms Wright Simpson’s 32-year-service with the agency ended on Friday when she retired.
The announcement comes only two days after a report released by the Veterans Affairs (VA) administration’s internal inspector general, Michael Missal, recommended she be disciplined.
The report alleged she changed an email to make it appear that her boss and his wife, Merle Bari, had been officially invited to Europe for an honorary dinner in Denmark when they had not.
Image copyrightGETTY IMAGESImage captionMr Shulkin and his wife Merle Bari
Mr Shulkin denies any wrongdoing but has reimbursed the government for his wife’s air fare, according to the Military Times.
“I do regret the decisions that have been made that have taken the focus off our [VA reform] work”, he said on Thursday, before Ms Wright Simpson’s retirement.
Five Trump cabinet officials have faced ethics probes related to travel costs.
Mr Shulkin remains under fire for other allegations in the report.
Mr Missal accused the secretary of improperly accepting Wimbledon tennis tickets from an organiser for the Invictus Games – a sports tournament for wounded veterans founded by the UK’s Prince Harry.
Veterans Affairs officials had told ethics advisers that the tickets were a gift from a friend, and thus allowed under government rules.
Mr Missal also alleged that a top Veterans Affairs aide made “extensive use of official time” to organise leisure activities for the secretary and his wife, and essentially acted as his “personal travel concierge”.
Image copyrightAFPImage captionSouth Africa’s new ruler will steer away from the conspiratorial culture that flourished under his predecessor
It is rare in a journalistic life that one gets to sit a few yards from a president as he announces his resignation and then, within the same 24 hours, stand in the presence of his successor as he is sworn in.
More so when it happens without a shot being fired or vast crowds taking to the streets.
But South Africa has always been a nation to surprise. And to infuriate. And to inspire.
It is like no other country I have ever reported from.
From my first experiences in the apartheid 1980s to the rise of President Cyril Ramaphosa, it has frequently havered between the possibility of disaster and triumph, sometimes accommodating both possibilities within the space of a single day.
The fall of Jacob Zuma came about, in part, because of several uniquely South African dynamics.
Unruly nation
It would never have happened without a strong constitution. This document was forged with painstaking care in the early to mid-1990s and is shaped by the memory of apartheid’s brutal excesses and the dictatorships which had caused such misery elsewhere on the African continent.
But the protections it enshrines – of free speech, democratic accountability, an independent judiciary – are also reflections of a national characteristic, what I would venture to call a redemptive fractiousness.
South Africans love to argue. And they have the gift of being able to laugh at themselves and their leaders.
Image copyrightAFPImage captionPresident Zuma took some persuading, but was eventually forced to quit
In the dying days of the Zuma government there was a typically South African flurry of dramatic rumours.
Zuma might declare a state of emergency and use the army to crush his opponents. Memories of PW Botha and the apartheid emergency of 1986 still haunt an older generation.
Then came a story that suggested Mr Ramaphosa was negotiating a deal that might see Mr Zuma given immunity from prosecution if he turned state witness in major corruption allegations.
Both were quickly debunked.
The South African military will never be allowed to occupy the space in national life that it did in the securocrat apartheid state.
Even Mr Zuma’s most ardent supporters can remember what happens when you put too much power into the hands of the soldiers.
As for immunity, it was always a nonsensical rumour. The new dispensation had no intention of beginning with a shabby deal that would, in any case, have been swiftly struck down by the courts.
Image copyrightAFPImage captionMr Ramaphosa knows that the rot in the ruling party runs deeper than Mr Zuma
So how is President Ramaphosa likely to govern? The man I have observed over nearly 30 years is likely to move quickly to reduce the influence of the different security and intelligence departments.
This will be a government led by a civilian schooled in the trade unions and civil society who never felt comfortable with the conspiratorial culture of some elements that returned from exile with the ANC.
Over coffee the morning after President Ramaphosa’s state-of-the-nation speech, my colleague Andrew Harding, who lived through two terms of Mr Zuma, summed up the change: “This will be a CEO presidency.”
Precisely. Civil servants are already nervously wondering about his plans for downsizing bloated government departments. There will be a war on government waste, and visits to government departments across the country, probably unannounced.
But in a moment of hope some caution is needed.
Just as in the days after apartheid the public discourse was filled with white politicians claiming they had never really supported apartheid, we can now expect many who thrived under President Zuma to declare themselves to have been ardent enemies of corruption all along.
Mr Zuma was undoubtedly the figurehead under whom so much venality flourished. But the rot runs deep in the ruling party.
The new president will move carefully, as always, but we can expect to see a steady edging out of those associated with the old regime.
Image copyrightAFPImage captionThis is South Africa’s chance to reclaim some of the moral leadership it offered the continent in the past
Some of them may fall because they find themselves embroiled in criminal proceedings. Others will be cold shouldered and outmanoeuvred.
Will this split Africa’s oldest liberation movement? I don’t believe so. With elections looming next year the party will pull together, recognising that Mr Ramaphosa offers the best hope of victory.
Beyond the party, South African society is calling for a reckoning on corruption. There were crooks at many levels of society who stole from state coffers, and many had links to the ANC.
The truth commission which followed apartheid saw the beneficiaries of apartheid continue a life of privilege much as they had done before. I sense South Africans do not wish to see a similar veil drawn over corruption.
There will be a “state capture” inquiry to join the other public processes which are forensically laying out the abuses of the Zuma years.
And there will be trials of those accused of abusing their power. Jacob Zuma could be among those in court.
Africa is undergoing profound political changes. But one cannot impose a single template and disregard the complex factors at work in different regions.
In the last few months I have witnessed the aftermath of elections in Kenya and Liberia, and the removal of unpopular leaders in Zimbabwe and South Africa.
In each place the dynamics were different.
Zimbabwe happened because the incumbent Robert Mugabe and his wife Grace alienated the security elite that had propped up their ruinous regime for so long.
In Liberia, the successful transition from one democratically elected leader to another, for the first time in the nation’s history, came about in the context of a broadening of democracy across much of west Africa.
In central and east Africa authoritarianism is the dominant force, for now.
But the peaceful removal of Jacob Zuma, led by the institutions of a vibrant democracy, will inspire activists in Kinshasa, Kigali, Kampala, Nairobi and numerous other points across the continent.
From the days when corruption and misrule threatened to make South Africa a laughing stock there is a chance to reclaim some moral leadership on the continent.
Image copyrightAFPImage captionKarimachiani, right, has been banned for six months
Wrestling’s global sporting body has banned an Iranian athlete for six months for deliberately throwing a match to avoid an Israeli opponent.
Alireza Karimachiani was winning a match against his Russian opponent in November’s under-23 world championships when his coach ordered him to lose.
If he had won, he would have faced an Israeli athlete in the next round.
Iran does not recognise the state of Israel and bans its athletes from competing against Israelis.
Iran’s wrestling federation has said it will challenge the ban, which was announced by the United World Wrestling Disciplinary Chamber on Friday.
“Karimachiani, on instruction of his coach Jamshidi, wilfully lost his 1/8 finals match against Alikhan Zhabrilov,” the chamber said, referring to the Russian opponent in the match.
“Both wrestler and coach were found to have acted in direct violation of the International Wrestling Rules… and the UWW Disciplinary Regulations,” it added.
Karimachiani’s ban was set to run for two years from the date of the incident – making him eligible to compete in late May 2018.
His coach, Hamidreza Jamshidi, was also banned from the sport until the end of November 2019.
During the November 2017 match-up in Poland, Karimachiani was leading 3-2 in the fourth minute of the match.
Winning would have set him up against Israel’s Uri Kalashnikov in the next bout.
Footage of the match appeared to contain a man’s voice shouting instructions to lose, before the match is briefly paused for an exchange between athlete and coach.
In the final 45 seconds, Karimachiani is tackled to the ground before he rolls over and over, resulting in his opponent winning 14-3.
Image copyrightEPAImage captionAuthorities did not say whether Mrs Mugabe herself will face charges
The vice chancellor of the University of Zimbabwe has been arrested in connection with an investigation into the awarding of a doctorate to former first lady Grace Mugabe.
Levi Nyagura was detained by the country’s anti-corruption agency, to be charged with abuse of office.
Mrs Mugabe was awarded a PhD just months after enrolling in 2014, despite it usually taking years to complete.
Members of the sociology department said they had not seen supporting evidence, and called for the nullification of her qualification and a full investigation.
The PhD’s authenticity was questioned because her thesis was not published alongside others at the time.
The document was only published online in January this year, four years after she graduated, and has been the subject of intense speculation since.
She was awarded the qualification by her husband and then-President Robert Mugabe, who was also the chancellor of the university at the time.
The doctorate title was used on campaign material for Mrs Mugabe as she became increasingly involved in politics.
In November Robert Mugabe was ousted from office after 37 years of rule amid growing speculation his wife was lining herself up to replace her aging husband in power.
