A senior Hamas official told AFP Sunday that the Palestinian militant group was withdrawing from talks on a ceasefire in the Gaza war because of Israeli "massacres" and its attitude in negotiations.

The senior official said Hamas political leader Ismail Haniyeh had told international mediators of the "decision to halt negotiations due to the occupation's (Israel) lack of seriousness, continued policy of procrastination and obstruction, and the ongoing massacres against unarmed civilians."

The official referred to Saturday's "brutal massacres" in the al-Mawasi camp for displaced persons in Khan Younis (south) and the al-Shati refugee camp in Gaza City.

Meanwhile, a top Hamas official told AFP that the group’s military leader Mohammed Deif is “fine” despite an Israeli attempt to kill him in an air strike.

"Commander Mohammed Deif is well and directly overseeing the operations of the Hamas military wing.”

Israel announced that it had targeted Mohammed Deif, the leader of the Izzedine al-Qassam Brigades, the armed wing of Hamas, and Rafa Salama, the commander of the Hamas brigade in Khan Younis, "in a fenced area run by Hamas" in southern Gaza, describing them as "the two planners of the 7 October massacre". Israeli Prime Minister Binyamin Netanyahu said on Saturday evening that "there is no certainty that either of them was eliminated".

The Hamas government's Ministry of Health reported on Sunday that the number of dead and wounded in al-Shati camp had risen to 45. According to the ministry's updated report, the death toll from the Israeli attack on al-Mawasi camp rose to 92, "half of them women and children," and 300 wounded.

Diplomatic efforts resumed this week under the auspices of Qatar, Egypt and the United States to broker a ceasefire in the Gaza Strip as the war entered its tenth month. Ismail Haniyeh on Saturday accused the Israeli prime minister of trying to prevent a ceasefire in the Gaza Strip through "heinous massacres" carried out by Israeli forces, according to a Hamas statement.
