Hamas handed over the remains of four more Israeli hostages in exchange for hundreds of Palestinian prisoners as part of the ceasefire in the Gaza Strip.

Hamas-led militants have released three gaunt, frail-looking Israeli hostages and Israel has freed 183 Palestinian prisoners in the fifth exchange of a ceasefire that has paused 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.
