A man carries a child following a suspected chemical attack in the Syrian town of Khan Sheikhoun in April. In the week after the attack, globalresearch.ca’s 10-most-tweeted articles were about the attack, including some that spread conspiracy theories.

Editor’s note: An earlier version of this story said that NATO is investigating a Canadian website for the online spread of pro-Russia propaganda. It is NATO’s Strategic Communications Centre of Excellence, not the alliance’s military command, that is looking into the matter. Also, the surname for the author of a book called Putin’s Praetorians is Phil Butler, not Phil Taylor as published.
