Only a few weeks ago, President Donald Trump seemed confident a deal was days away that would end the fighting in Gaza, secure the release of hostages and allow aid to flow into an enclave where people are starving to death.

President Trump’s special envoy said that “we will now consider alternative options to bring the hostages home,” though it was not clear that negotiations had halted.

Israeli Prime Minister Benjamin Netanyahu said Friday his government was considering “alternative options” to ceasefire talks with Hamas after Israel and the U.S. recalled their negotiating teams, throwing the future of the negotiations into further uncertainty.

It marks the latest setback in efforts to secure a deal that would bring a ceasefire to Gaza and secure the release of Israeli hostages held by Hamas.

Israel is reviewing a revised response from Hamas to a proposed ceasefire and hostage-release deal, Prime Minister Benjamin Netanyahu's office said on Thursday, as Israeli air and ground strikes continued to pound the Gaza Strip.

Hamas has reportedly taken steps to fend off possible Israeli military plans aimed at rescuing the 50 remaining hostages in Gaza.

Gaza health officials and the ambulance service say at least 25 people were killed by Israeli airstrikes and gunshots overnight as ceasefire talks appear to have stalled and Palestinians in Gaza are facing famine.
