When the mother of one of the Thai hostages held in the Gaza Strip for over a year caught sight of her son on a Facebook livestream after his release Thursday, he had changed so much that she didn’t recognize him at first.

Hamas released eight hostages, including three Israelis and five Thais, as part of a hostage-for-prisoner exchange.

Israel delayed the release of 110 Palestinian prisoners for several hours after broadcast images showed crowds jostling and cheering in Gaza as Israeli and Thai hostages were handed over to the Red Cross earlier that day.
