Israeli Prime Minister Benjamin Netanyahu has indefinitely delayed the release of what would have been the biggest group of Palestinian prisoners so far

JERUSALEM (AP) — Hamas is set to free six more Israeli hostages Saturday from the Gaza Strip, but the exchange for hundreds of Palestinian prisoners is shadowed by heightened tension between the adversaries that clouds the future of the fragile ceasefire deal.

Israel and Hamas on Sunday accused each other of violating the already fragile Gaza Strip ceasefire deal after Israel delayed the release of hundreds of Palestinian prisoners who were supposed to be exchanged for hostages.

Hamas released six hostages from Gaza on Saturday, handing over in two public ceremonies and one private transfer the final living captives in this phase whom the warring sides agreed would be freed when a ceasefire began last month.

Israel’s security cabinet held an emergency meeting Tuesday following word from Hamas that three Israel hostages would not be released Saturday as agreed.

President Donald Trump's Middle East envoy Steve Witkoff will travel to the Middle East this week, he said on Sunday, to push for the extension of a fragile Gaza ceasefire between Israel and Hamas. The three-stage ceasefire which came into effect on January 19 is now nearing the end of its first phase.

President Donald Trump's envoy Steve Witkoff will return this week to the Middle East, where he will seek an "extension" of Phase One of the ceasefire deal.

White House envoy Steve Witkoff will travel to the Middle East on Wednesday to discuss with Israel, Qatar and Egypt the possibility of extending the first phase of the Gaza hostage and ceasefire deal.

President Donald Trump's Middle East envoy Steve Witkoff said on Sunday the U.S. expects the second phase of the Israel-Hamas ceasefire deal to go forward and that he would visit the Middle East in the coming week.
