Microsoft’s Threat Analysis Center, which reviewed the video at NBC News’ request, said it appears to have come from a known Russian disinformation group.

A video spreading on X and Telegram of a man purporting to be a Hamas fighter threatening the Olympics in Paris is part of a Russian-linked disinformation campaign meant to disrupt the event, according to researchers at Microsoft.

On Telegram, Hamas official Izzat al-Risheq denied the video had come from Hamas, calling it a forgery.

Researchers from Microsoft’s Threat Analysis Center, who reviewed the video at NBC News’ request, said it appears to have come from a known Russian disinformation group, noting that details of a previous video about Ukraine match it.
