A top level Israeli security delegation arrived in Qatar on Sunday for talks on a Gaza hostage and ceasefire deal, a spokesperson for Israeli Prime Minister Benjamin Netanyahu said, in a possible sign of so-far elusive agreements nearing.

Qatar and fellow mediators Egypt and the United States are making renewed efforts to reach a deal to halt the fighting in the enclave and free the remaining 98 hostages held there before President-elect Donald Trump takes office on Jan. 20.

Netanyahu’s office said on Saturday that the delegation includes Mossad Head David Barnea, the head of the Shin Bet domestic security service Ronen Bar and the military’s head of the hostage brief, Nitzan Alon.

Trump’s Middle East envoy, Steve Witkoff, met on Saturday with Netanyahu, after having met on Friday with Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani.

Israeli and Palestinian officials have said since Thursday that some progress has been made in the indirect talks between Israel and militant group Hamas but did not elaborate. The sides have been keeping a tight lid on the details being worked out.

It is unclear how they will bridge one of the biggest gaps that has persisted throughout previous rounds of talks: Hamas demands an end to the war while Israel says it won’t end the war as long as Hamas rules Gaza and poses a threat to Israelis.

Israel launched its assault in Gaza after Hamas fighters stormed across its borders in October 2023, killing 1,200 people and taking more than 250 hostages, according to Israeli tallies.

Since then, more than 46,000 people have been killed in Gaza, according to Palestinian health officials, with much of the enclave laid to waste and gripped by a humanitarian crisis, and most of its population displaced.
