Burma mobs 'kill 30 Rohingyas'

More than 30 Rohingya Muslims were killed in attacks by Buddhists last week in Burma's Rakhine state, the BBC has been told.

Sources told the BBC that a mass killing had taken place, with local Buddhists and security forces taking part in the attack.

Tin Htar Swe from the BBC's Burmese Service said it was unclear what had caused the tension.
