Israel and Hamas have resumed ceasefire talks in Qatar, both sides said, even as Israeli forces ramped up a bombing campaign that has killed hundreds of people over 72 hours, and mobilised for a massive new ground assault.
Palestinian health authorities said at least 146 people had been confirmed killed in the third day of Israel's latest bombing campaign, one of the deadliest waves of strikes since a ceasefire collapsed in March.
Many hundreds more wounded were being treated in hospital, and countless others were still buried under rubble.
Israel says it is mobilising to seize more ground in Gaza in a new campaign dubbed "Operation Gideon's Chariots", which follows a visit this week to the Middle East by US President Donald Trump.
It has halted all supplies entering Gaza since the start of March, leading to rising international concern over the plight of the enclave's 2.3 million residents.
Taher Al-Nono, the media advisor for the Hamas leadership, told Reuters a new round of indirect talks with the Israeli delegation in Doha began on Saturday, discussing all issues "without pre-conditions".
"The Hamas delegation outlined the position of the group and the necessity to end the war, swap prisoners, the Israeli withdrawal from Gaza, and allowing humanitarian aid and all the needs of the people of Gaza back into the strip," he added.
Israeli Defence Minister Israel Katz also said in a statement that negotiations on a deal to release Israeli hostages held by Hamas had resumed in Doha. He noted that the talks had started without Israel first agreeing to a ceasefire or to lift its blockade.
Israel's military said it was conducting extensive strikes and mobilising troops with the aim of achieving "operational control" in parts of Gaza.
Gaza health authorities said most of those killed today were in towns on the northern edge of the enclave, including Beit Lahiya and the Jabalia refugee camp, as well as in the southern city of Khan Younis. They said 459 people had been injured.
Israeli forces had told people to leave the northern areas yesterday.
"Northern Gaza is witnessing a systematic campaign of extermination," Hamas said in a statement, calling on Arab leaders at a summit in Baghdad to take practical steps to stop the aggression and ensure the delivery of aid.

Talks since March have failed to restore a truce under which Hamas would release remaining hostages captured in the October 2023 assault on Israel that precipitated the war.

United Nations experts say famine now looms in Gaza more than two months after Israel halted all deliveries of supplies.UN aid chief Tom Fletcher asked the Security Council this week if it would act to "prevent genocide".
Israel blames Hamas for the suffering of civilians for operating among them and hijacking aid, which Hamas denies. Israel says enough food reached Gaza during the six-week ceasefire at the start of the year to stave off hunger for now.
Yesterday, Mr Trump acknowledged Gaza's growing hunger crisis and the need for aid deliveries.
A US-backed foundation aims to start distributing aid to Gazans by the end of May using private US security and logistics firms. The UN has said it will not work with the group because it is not impartial, neutral or independent.
Gaza's health system is barely operational with hospitals hit repeatedly by the Israeli military during the 19-month war and medical supplies drying up.
The head of the Indonesian Hospital in northern Gaza, Marwan Al-Sultan, said huge numbers of wounded victims of the latest bombing campaign were in critical condition.
"Since midnight, we have received 58 martyrs, while a large number of victims remain under the rubble. The situation inside the hospital is catastrophic," he said on X.
Israeli Prime Minister Benjamin Netanyahu said on 5 May that Israel was planning an expanded, intensive offensive against Hamas as his security cabinet approved plans that could involve seizing the entirety of Gaza and controlling aid.
French President Emmanuel Macron said last night that the humanitarian crisis in Gaza was intolerable, and added that he hoped to discuss the matter soon with Mr Netanyahu and US President Donald Trump.
His comments came as Taoiseach Micheál Martin joined six other European leaders condemning what they described as "the man-made humanitarian catastrophe taking place before our eyes in Gaza".
