Thai officials on Thursday said remains handed over to Israel by militants in Gaza have been identified as belonging to the last Thai hostage taken during the October 7, 2023, attack that launched the war.

The Thai Ministry of Foreign Affairs said it was notified by Israeli authorities that the remains of a hostage that were returned on Wednesday were identified as Sudthisak Rinthalak, a Thai man who was an agricultural worker in Israel.

Remains militants handed over Tuesday did not match either of the last two hostages.

The return of all the hostages taken during the attack that started the war is a key element of the first phase of the U.S.-brokered ceasefire that began in October, which both Hamas and Israel have accused the other of breaking. In exchange, Israel has been releasing Palestinian prisoners.

Nikorndej Balankura, the Thai Foreign Ministry's spokesperson, said that Sudthisak’s family has been notified. He added that Sudthisak was killed on the day of the attack, and his body was taken into Gaza.

He thanked the Israeli government for their assistance that led to the release of all 31 Thai hostages taken at the start of the war. Of them, 28 were returned alive and three dead.
