Facebook parent Meta Platforms Inc. is facing mounting legal challenges by Rohingya refugees who blame the social media company for inciting genocidal violence in 2017 against the Muslim minority in Myanmar.

The company allowed an "out-of-control spread of anti-Rohingya content” despite repeated warnings from civil society groups and human rights activists about its deadly consequences, according to a complaint filed Monday in state court in California.

Separately, members of the Rohingya community from Myanmar who now live in the U.K. and in refugee camps in Bangladesh told Meta they intend to pursue a lawsuit in the U.K.’s High Court over its failure to take action against hate on its platform.
