Talks aimed at securing a ceasefire in Gaza are stalling over the extent of Israeli forces' withdrawal from the Palestinian enclave, Palestinian and Israeli sources familiar with the negotiations in Doha said on Saturday.

The European Union and Israel have agreed on a deal to allow more food, fuel and other vital aid into the starvation-gripped Gaza Strip, with an E.U. presence at border crossings, European and Israeli officials said Thursday.

"The situation is very catastrophic because the electricity will abruptly go off within 24 hours," one doctor warned.

The decision followed discussions with the European Union, which has pressed Israel to ease the dire humanitarian conditions for Palestinians in the territory.

Medical workers are forced to make life-or-death decisions for patients whose injuries would be treatable if they had the supplies, according to a new report.

The fighting in Gaza has shown no sign of slowing as Prime Minister Benjamin Netanyahu meets with President Donald Trump in Washington this week to work on a U.S.-led ceasefire plan.

Speaking on condition of anonymity, the official said no permanent ceasefire would be possible without the complete removal of Hamas.
