Facebook's algorithm helped fuel the viral spread of hate and violence during Ethiopia's civil war, a legal case alleged, reports BBC.
Abrham Meareg, the son of an Ethiopian academic shot dead after being attacked in Facebook posts, is among those bringing the case against Meta.
They want a $2bn fund for victims of hate on Facebook and changes to the platform's algorithm.
Meta said it invested heavily in moderation and tech to remove hate.
Tens of thousands of people have died in the conflict between the Ethiopian government and forces in the northern Tigray region, with 400,000 others living in famine-like conditions.
