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.

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.
