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, the BBC reports.
Palestinian militants have fired more than 450 rockets into Israeli territory since Saturday. Israel says most 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 four 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”.
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.
The violence 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.
