A branch of the Russian-owned news outlet Sputnik reported as real a fake story that Israel had used a nuclear weapon on Syria from YourNewsWire, a fake news site that experts have described as a Russian proxy and a pusher of Russian-supported narratives.

Nonetheless, on that same day, Sputnik Arabic published a piece with the headline (as translated by Google) Israel bombed Syria with its first tactical nuclear bomb that directly linked to YourNewsWires fake story. Sputnik also posted its story on its Facebook page, writing (based on Facebooks translation) that there were allegations that Israel used a nuclear weapon on Syria.
