Hamas identified the three Israeli hostages that it plans to free in the next release mandated by the fragile ceasefire agreement, a sign the deal was moving forward Friday even as U.S. and Israeli officials continued calls to relocate Gaza's population after the war.

Hamas on Friday announced the names of three Israeli hostages to be released on Saturday in exchange for Palestinian prisoners after a delay that underlined the obstacles hanging over a fragile deal meant to end the war in Gaza.

It is believed that at least two of the six American hostages still held in Gaza are alive — Sagui Dekel-Chen, 35, who grew up in Bloomfield, Connecticut, and Edan Alexander, 19, from Tenafly, New Jersey. Four other Americans are believed to have been killed in captivity.
