The Israeli military has committed to continuing its “protracted” and “difficult” operation in Gaza, expanding ground operations in both the southern and northern Gaza Strip.
Despite calls for a ceasefire and humanitarian truce, Israel’s Prime Minister Benjamin Netanyahu stated that the war will persist until all Israeli goals are achieved.
The US, while emphasizing the critical need to protect civilians, has not requested a ceasefire.
The UN Security Council approved a resolution for large-scale aid deliveries to Gaza but did not explicitly call for a ceasefire.
Talks in Egypt for a new truce have yet to yield results.
The Hamas-run health ministry says more than 20,000 people have been killed and 54,000 injured in Gaza since the war began. Most of the dead are women and children, Hamas says.
Israel says it takes steps to avoid civilian casualties, and blames Hamas for embedding itself in densely-populated areas.
Meanwhile, the IDF has announced that 14 of its soldiers have been killed in fighting in Gaza since Friday, bringing the total to more than 150.
Responding to the deaths, Mr Netanyahu said on Sunday that the war was exacting a “very heavy price” on Israel, but that there was “no choice but to keep fighting”.
Israel says 700 Palestinian militants have been arrested since it launched its military operation and invasion of Gaza with the aim of eliminating Hamas.
The Israeli operation began after Hamas fighters crossed from Gaza into southern Israel on 7 October, killing 1,200 people and taking about 240 hostages.
Mr Netanyahu and Mr Biden discussed Israel’s operation in Gaza in a phone call on Saturday.
Mr Biden “emphasised the critical need to protect the civilian population including those supporting the humanitarian aid operation, and the importance of allowing civilians to move safely away from areas of ongoing fighting”, the White House said.
Mr Netanyahu “made it clear that Israel would continue the war until all of its goals have been achieved”, the Israeli PM’s office said.
In its update on Sunday, the Hamas-run health ministry said at least 166 people had been killed and 384 injured in the previous 24 hours.
The Israeli military has kept up its bombing campaign in Gaza – ordering civilians to flee.
On Saturday, it said one of its fighter jets had killed Hassah Atrash, a man it accused of smuggling weapons into Gaza to arm Hamas. There was no confirmation from Hamas.
The Israeli military has said it has almost full operational control of the north of the Gaza Strip, and is stepping up operations in the south.
The UN said the latest evacuation order affected 150,000 people in the middle of the territory.
