Late Monday afternoon, about the same time the FBI warned about Russia and other countries using social media to influence the US midterm elections, Facebook released a report showing the company's platform was used to foment violence against the Rohingya in Myanmar.

The Rohingya, a minority mostly Muslim ethnic population of about 1.3 million people, face persecution in Myanmar (the country formerly known as Burma), where the majority of the country identifies as Buddhist, the rule of law remains fragile, and the army is a powerful political force.
