Israeli forces appeared to have withdrawn from the Jenin and two other refugee camps in the occupied West Bank after a more-than weeklong military operation that left dozens dead and a trail of destruction.
Israel says the large-scale raids in the territory were aimed at dismantling militant groups and preventing attacks. Palestinians fear a widening of the war in Gaza.
Senior Hamas leader Khalil al-Hayya accused Israeli Prime Minister Benjamin Netanyahu of deliberately stalling cease-fire negotiations, and urged the United States and the international community to put more pressure on Israel.
The United Nations says the humanitarian situation in Gaza is "beyond catastrophic," with more than 1 million Palestinians not receiving any food rations in August and a 35% drop in people getting daily cooked meals. Health workers resumed vaccinating children against polio in the southern Gaza Strip early Friday for the second phase of a massive immunization campaign.
The war began after Hamas launched a wide-scale attack into Israel on Oct. 7, killing some 1,200 people, mostly civilians, and abducting around 250 people. Israel's campaign in response has killed more than 40,000 Palestinians, according to the Gaza Health Ministry, which does not differentiate between civilians and fighters in its toll.
