Hersh Goldberg-Polin was taken by Hamas into Gaza on 7 October

The parents of Israeli-American hostage in Gaza have urged him to "stay strong" and "survive" after Hamas released a proof-of-life video.

Hersh Goldberg-Polin, 23, is seen without his lower left arm in the short clip. It was blown off during Hamas's 7 October attack on southern Israel.

The footage is undated, but he says he has been held for almost 200 days.

In response, his mother Rachel and father Jon appealed for more to be done to secure a new hostage release deal.
