The parents of an 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 and father appealed for more to be done to secure a new hostage release deal.

They urged Israel, Hamas and mediators the US, Egypt and Qatar to "get a deal done" to reunite "all of us with our loved ones and end the suffering in this region".
