Hamas is “studying” an Israeli proposal for a ceasefire in Gaza that would see 10 hostages released in exchange for hundreds of Palestinian prisoners and detainees, an official with the militant group told CNN.

Hostages released earlier this year are adding their powerful voices to calls for a deal to bring home those still held by Hamas.

Hamas said on Monday (Apr 15) that Israel has offered a 45-day ceasefire if it releases half of the remaining hostages held in Gaza, which the United Nations said is now in the grip of its worst humanitarian crisis since the start of the war.
