JERUSALEM (AP) — Hamas released a hostage video on Wednesday showing a well-known Israeli-American man who was among scores of people abducted by the militants in the attack that ignited the war in Gaza.

The video was the first sign of life of Hersh Goldberg-Polin since Hamas’ Oct. 7 attack on southern Israel, and its release ignited new protests in Jerusalem calling on the government to do more to secure the captives’ release.

In the video, Goldberg-Polin accused Israel’s government of abandoning the people who are being held hostage by Hamas. He also claimed that some 70 captives have been killed in Israel’s bombing campaign. Goldberg-Polin was clearly speaking under duress, and the claim could not be independently verified. It was not clear when the video was made.

Goldberg-Polin, 23, was at the Tribe of Nova music festival when Hamas launched its attack from nearby Gaza. In the video, Goldberg-Polin is missing part of his left arm.
