Talks to reach a Gaza ceasefire and hostage release deal between Israel and Hamas are 90% complete, but key issues remain that need to be bridged, a senior Palestinian official involved in the talks told the BBC.

U.S. officials say both Hamas and Israel are making concessions toward securing a deal, but tempered optimism with differences remaining on key issues.

U.S. and Arab mediators are working round-the-clock to hammer out a ceasefire deal between Israel and Hamas, sources close to the talks said, while in the Gaza Strip medics said Israeli strikes had killed 13 Palestinians on Thursday.

Israeli officials say a ceasefire in Gaza is a more realistic prospect than at any time in the past year, suggesting a long-awaited deal to free hostages and boost aid to the beleaguered territory could be close.

Khan Yunis, Gaza Strip - 16, 2024 The ongoing talks on ceasefire in Gaza have gained momentum, as Hamas announced on Saturday that leaders of three Palestinian factions believe a ceasefire agreement is "closer than ever" if Israel refrains from imposing new conditions.
