A handful of U.K. and U.S. law firms have taken roles to advise refugees of the Rohingya genocide in legal proceedings against Meta, formerly known as Facebook, in which the refugees accuse the social media giant of allowing the spread of hate speech against them.

The refugees are seeking $150 billion in compensation as part of the claims, which allege that Facebook allowed for the persecuted minority group to become the subject of violence on the platform.
