American Judith Weinstein, who was believed to have been kidnapped by Hamas, was killed by the Palestinian group on Oct. 7 when it attacked Israel, President Joe Biden has said, adding he was devastated by the news.

Weinstein, 70, was also an Israeli and the last missing Canadian from the Oct 7 attack. Last week Biden said her husband, Gadi Haggai, 73, was killed on Oct 7.

“This tragic development cuts deep, coming on the heels of last weeks news that Judiths beloved husband, Gad Haggai, is believed to have been killed by Hamas,” Reuters quotes Biden as saying in a statement. The US president vowed to continue attempting for the release of other hostages still held by Hamas.
