New footage of six Israeli hostages shows them celebrating the Jewish holiday of Hanukkah while being held captive in a tunnel in Gaza, several months before they were killed.

Israel said all six were killed last August by Hamas, shortly before Israeli troops arrived.

The Israeli Health Ministry said that autopsies had determined the hostages were shot at close range.

The videos and photos were published Thursday for the first time by the forum representing hostage families. They show Israeli-American Hersh Goldberg-Polin, 23; Ori Danino, 25; Eden Yerushalmi, 24; Almog Sarusi, 27; Alexander Lobanov, 33; and Carmel Gat, 40, filmed under duress, walking through a tunnel in Gaza, playing cards on the floor and lighting the holiday candles.

The forum said the footage was found in Gaza and documented the hostages' months in captivity.

The series of short videos and photos shows the hostages seated on blankets on the floor, at times embracing one another and saying prayers over the Hanukkah candles. In one video they're heard counting down and wishing each other a happy new year.
