Israel and militants in the Gaza Strip have stepped up their attacks on each other, in some of the most intense exchanges in recent years.
Palestinian militants have fired more than 450 rockets into Israeli territory since Saturday. Israel says many were intercepted but one man was killed.
The Israel Defense Forces (IDF) say they have struck about 220 targets in the Gaza Strip over the weekend.
The Palestinians say six people were killed in those strikes.
On Sunday, Israeli Prime Minister Benjamin Netanyahu said he had ordered the military to “continue its massive strikes on terror elements in the Gaza Strip”.ADVERTISEMENT
The flare-up comes despite a truce agreed last month. Egypt and the United Nations have recently been trying to broker a longer-term ceasefire.
How did the latest round of violence develop?
It began on Friday, during protests in Gaza against the blockade of the area – which Israel says is needed to stop weapons reaching militants.
A Palestinian gunman shot and wounded two Israeli soldiers at the boundary fence. Israel retaliated with an air strike that killed two militants.
The rocket barrage from Gaza began on Saturday morning. Israel’s Iron Dome missile defence system shot down dozens of the rockets, but a number of homes in Israeli towns and villages were hit.
An Israeli man died early on Sunday in Ashkelon, 10km (six miles) north of Gaza, after being struck by shrapnel in his home.
On the previous day, an elderly Israeli woman suffered serious injuries in Kyriat Gat, to the east of Ashkelon.
Israel air strikes targeted sites belonging to the militant groups Hamas and Islamic Jihad on Saturday and Sunday.
Hamas, which controls Gaza, says four Palestinian men were killed, as well as a woman and her 14-month-old daughter.
But Israel says the mother and baby may have been killed by a Palestinian rocket that fell short of its target.
The sites destroyed include a multi-storey building in Gaza City, which Israel said included Hamas intelligence offices.
Turkey said its state news agency Anadolu had an office there. Foreign Minister Mevlut Cavusoglu called Israeli strikes on civilians “a crime against humanity”.
What about previous flare-ups?
It is the first deadly rocket attack from Gaza since the conflict of July and August 2014.
In that year, an Israeli ground offensive on Gaza resulted in the death of 67 Israeli soldiers. Hamas and its allies launched 4,000 rocket and mortar strikes that killed six civilians in Israel.
On the Palestinian side, 2,251 people, including 1,462 civilians, were killed in the seven-week conflict, according to the UN.
Since then, Palestinian militants have continued to carry out sporadic strikes on Israel.
In a previous wave this year, in March, several rockets were fired into southern Israel, triggering raids on Gaza by the Israeli air force. No fatalities were reported on either side.
In early April a ceasefire was brokered by Egypt, but Hamas and allied militant groups later accused Israel of violating its terms.
