An Israeli official said on Saturday the government had an "intention" to renew "this week" talks aimed at reaching a hostage release deal in Gaza, after a meeting in Paris between US and Israeli officials.

"There is an intention to renew the talks this week and there is an agreement," the official said, on condition of anonymity.

The Israeli official did not elaborate on the agreement, but Israeli media reported that Mossad chief David Barnea had agreed during meetings in Paris with mediators CIA Director Bill Burns and Qatari Prime Minister Mohammed bin Abdulrahman Al-Thani on a new framework for the stalled negotiations.

Top US diplomat Antony Blinken also spoke with Israeli war cabinet minister Benny Gantz about new efforts to achieve a ceasefire and reopen the Rafah border crossing, Washington said.

Talks aimed at reaching a hostage release and truce deal in the Gaza Strip ground to a halt this month after Israel launched a military operation in the territory's far-southern city of Rafah.

The Gaza war broke out after Hamas's October 7 attack resulted in the deaths of more than 1,170 people, mostly civilians, according to a based on Israeli official figures.

Militants also took 252 hostages, 121 of whom remain in Gaza, including 37 the army says are dead.

Israel's retaliatory offensive has killed at least 35,903 people in Gaza, mostly women and children, according to data from the Hamas-run territory's health ministry. (AFP)
