Malaysian Prime Minister Najib Razak has said he was "deeply concerned" by the discovery of mass graves of at least 100 suspected Rohingya migrants in the border town of Padang Besar and vowed to find those responsible.
The government revealed on Sunday that mass graves were found near jungle camps along the border with Thailand, reported abc.net.au.
Officials are yet to confirm the number of bodies in the graves and their locations.
The discovery came after Thailand police found secret human-trafficking camps on their side of the border and dozens of shallow graves, earlier this month.
