The Israeli military said Hamas turned over what it said were the remains of four Israeli hostages for the exchange of dozens of Palestinian prisoners.

Hamas says that it will return the bodies of four dead hostages on Thursday in exchange for Israel’s release of hundreds of Palestinian prisoners.

Palestinian teenagers detained by Israel and released back to Gaza recounted being mistreated in Israeli detention upon arriving home Thursday. Many appeared gaunt, but smiling, as they waved to relatives from the buses ferrying them from Israeli detention back to Gaza.
