Survivor describes fleeing mass shootings in Sudan's al-Fashir

Fighters riding camels rounded up a couple of hundred men near the Sudanese city of al-Fashir and brought them to a reservoir, shouting racial slurs before starting to shoot, according to a man who said he was among them but escaped. Survivors' accounts from nearby Tawila add to others of abuses by the Rapid Support Forces paramilitaries as they took al-Fashir from the Sudanese army. Lucy Fielder reports.
