Hamas says no interim truce possible without work toward permanent ceasefire deal

CAIRO (Reuters) -Hamas' armed wing spokesperson said on Friday that while the group favours reaching an interim truce in the Gaza war, if such an agreement is not reached in current negotiations it could revert to insisting on a full package deal to end the conflict.

Hamas has repeatedly offered to release all the hostages held in Gaza and conclude a permanent ceasefire agreement, and Israel has refused, Abu Ubaida added in a televised speech.

Arab mediators Qatar and Egypt, backed by the United States, have hosted more than 10 days of talks on a U.S.-backed proposal for a 60-day truce in the war that has laid waste to the Palestinian enclave.

As part of the potential deal, 10 hostages held in Gaza would be returned along with the bodies of 18 others, spread out over 60 days. In exchange, Israel would release a number of detained Palestinians.

"If the enemy remains obstinate and evades this round as it has done every time before, we cannot guarantee a return to partial deals or the proposal of the 10 captives," said Abu Ubaida.

Disputes remain over maps of Israeli army withdrawals, aid delivery mechanisms into Gaza, and guarantees that any eventual truce would lead to ending the war, said two Hamas officials who spoke to Reuters on Friday.

The officials said the talks have not reached a breakthrough on the issues under discussion.

Hamas says any agreement must lead to ending the war, while Israeli Prime Minister Benjamin Netanyahu says the war will only end once Hamas is disarmed and its leaders expelled from Gaza.
