Indirect talks between Hamas and Israel for a ceasefire in Gaza are being held up by Israel's proposals to keep troops in the territory, two Palestinian sources with knowledge of the discussions told AFP on Saturday.

Delegations from both sides began discussions in Qatar last Sunday to try to agree on a temporary halt to the 21-month war sparked on October 7, 2023.

Both Hamas and Israel have said that 10 living captives who were taken that day and who are still in captivity would be released if an agreement for a 60-day ceasefire were reached.

But one well-informed Palestinian source said Israel's refusal to withdraw all of its troops from Gaza was holding back progress on securing a deal.

"The negotiations in Doha are facing a setback and complex difficulties due to Israel's insistence, as of Friday, on presenting a map of withdrawal, which is a map of redeployment and repositioning of the Israeli army rather than a genuine withdrawal," the source said.

Hamas has said it wants the complete withdrawal of Israeli troops from Gaza, which is home to more than two million people.

The source said, however, that the Israeli delegation presented a map at the talks which proposed maintaining military forces in more than 40 per cent of the Palestinian territory.

"Hamas's delegation will not accept the Israeli maps... as they essentially legitimise the reoccupation of approximately half of the Gaza Strip and turn Gaza into isolated zones with no crossings or freedom of movement," the source added.

Mediators have asked both sides to postpone the talks until the arrival of US President Donald Trump's special envoy, Steve Witkoff, in Doha, they added.

A second Palestinian source said "some progress" had been made on plans for releasing Palestinian prisoners and getting more aid to Gaza.

But they accused the Israeli delegation of having no authority, and "stalling and obstructing the agreement to continue the war of extermination".
