Newly released video shows 3 hostages, including Israeli-American, being taken captive on Oct. 7

The families of three men taken hostage by Hamas, including a well-known Israeli-American, have authorized the release of a video documenting the kidnapping near the Israel-Gaza border on Oct. 7.

Bring Them Home Now, a group that represents the hostages' families, shared the video on social media Monday after the Israeli army declassified it. 

In the video, which is graphic and hard to watch, Palestinian militants are seen carting three hostages, including Hersh Goldberg-Polin, 23, in the back of a white pickup truck that speeds through southern Israel back toward Gaza. Goldberg-Polin sits bloodied, his forearm a mangled stump. Hamas has since released a video of him in captivity with part of his left arm amputated.
