Hamas said its delegation had left Cairo on Thursday amid ongoing negotiations on a ceasefire accord in Gaza that mediators hope to achieve before the start of Ramadan early next week.

After four days of talks mediated by Qatar and Egypt to secure a 40-day ceasefire ahead of the Muslim fasting month there is still no sign of progress on key sticking points, with both sides blaming the other.

"Hamas's delegation left Cairo this morning for consultation with the leadership of the movement, with negotiations and efforts continuing to stop the aggression, return the displaced and bring in relief aid to our people," a Hamas statement said.

Senior Hamas official Sami Abu Zuhri said Israel had been "thwarting" efforts to conclude a ceasefire deal.

Abu Zuhri said that Israel was rejecting Hamas's demands to end its offensive in the enclave, withdraw its forces, and ensure freedom of entry for aid and the return of displaced people.

Israeli Prime Minister Benjamin Netanyahu reiterated his intention on Thursday of pressing on with the military campaign in Gaza. Israel has previously said its aim is to destroy Hamas and that any ceasefire must be temporary. It has also pressed for a list of hostages still alive and held by Hamas in Gaza.

The deal presented to Hamas for Gaza would free some of the hostages it still holds following the October 7 attack, in which Israel said 1,200 people were killed and 253 abducted. Palestinian prisoners held in Israel would also be released. (Reuters)
