Israel’s ambassador to Austria, David Roet, has suggested executing Palestinian minors involved in armed conflict, a secretly recorded video has revealed.

During a closed-door meeting with the local Jewish community in Innsbruck on Thursday, Roet said that “there should be a death sentence” for teenagers for “holding a gun” or a “grenade”. He provided no evidence of children carrying weapons in Gaza.

The video was recorded two days after Israel broke the Gaza ceasefire on 18 March, by which time more than 500 Palestinians were killed, of which almost 200 were children.

Roet dismissed concerns over civilian casualties in Gaza, stating: “If you believe that there are no uninvolved [people] in Gaza… you’re believing that Israel is targeting babies intentionally, which is not correct.”
