An Israeli air strike killed four Palestinians in Gaza on Tuesday, the territory's civil emergency service said, as Arab mediators and the United States tried to hammer out differences between Hamas and Israel over a January 19 ceasefire agreement.
The Israeli military said its air force attacked "terrorists who were engaged in a suspicious activity on the ground in central Gaza and posed a threat to the force."
Israel sent a delegation to the Qatari capital, Doha, for more ceasefire talks, and Hamas leaders ended a round of talks in Cairo earlier this week. But there has been no sign of a breakthrough to resolve the disputes that threaten a return to armed conflict, according to Reuters.
Fighting in Gaza has been halted since January 19 under a first phase of the truce, and Hamas has exchanged 33 Israeli hostages and five Thais for some 2,000 Palestinian prisoners and detainees.
Hamas wants to begin talks on a second phase that was supposed to reach an agreement over Israel's full pullout from the enclave. Israel demands that Hamas free the remaining hostages without beginning phase two negotiations.
On Tuesday, Hamas accused Israel of trying to cause famine in Gaza by continuing to suspend the entry of aid and also by its decision to sever its last working line of electricity to the enclave, a move that impacted a water desalination and sewage treatment facility.
"We call on mediators to pressure the occupation to abide by its pledges and open the crossings immediately, to ensure the flow of humanitarian aid and end the policy of collective punishment pursued by the occupation authorities against our people," it said in a statement.
Israel cut aid flows of food, medicine, and fuel imports earlier this month, a move it said was designed to pressure militant group Hamas in ceasefire talks. On Sunday, it announced an electricity cut, which aid groups say would deprive Gazans of clean water.
There is a risk that Gaza will experience another hunger crisis if Israel continues to block aid, the head of the UN Palestinian relief agency (UNRWA) in Gaza said on Monday, warning the situation is quickly deteriorating.
"I think the more we go ahead (with aid blockages), the more we will see the impact increasing on the population. And obviously, the risk ... is that we go back to situation we experienced months ago about deepening hunger in the Gaza Strip," said UNRWA Commissioner-General Philippe Lazzarini.
