Israel and Hamas are once again struggling to reach a ceasefire that could wind down the 15-month war in Gaza and bring home dozens of Israelis held hostage.

Israel says Hamas has not provided any information about the status of those 34 hostages, dampening any notion that the endorsement is a step toward a deal to stop the war.

Hamas has released a video showing a 19-year-old Israeli captive, as indirect talks between the group and Israel on a ceasefire and hostage release deal resume in Qatar. The footage shows Liri Albag calling for the Israeli government to reach a deal.

The White House is hoping to see a ceasefire agreement between Israel and Hamas concluded before Joe Biden leaves office, Antony Blinken has said.

Palestinian militant group Hamas has approved a list of 34 hostages presented by Israel to be exchanged in a possible ceasefire deal, a group official told Reuters on Sunday.

Hamas has named 34 hostages, some of them believed to have died in captivity, who it says it would return to Israel in the first phase of an evolving if still elusive ceasefire in Gaza.
