Malaysian police has announced the discovery of 139 mass graves of various sizes scattered across 27 sites in the northern state of Perlis.

According to Malaysia’s I nspector-General of the Police, Khalid Abu Bakar, Malaysian authorities unearthed the graves in Wang Kelian, a forest near the Thai-Malaysian border on May 11 as part of the special operation “Ops Wawasan Khas.”

At a press conference held in Wang Kelian, Khalid said it was still unclear how many bodies were buried in the graves as excavations only commenced on May 25.

The police operation was launched to investigate human trafficking camps set up in Malaysia by human trafficking gangs.

On May 1, Thailand discovered large graves near the border and 33 excavated bodies of alleged migrants.

Last weekend, Indonesia and Malaysia agreed to receive 7,000 refugees from Bangladesh and the Burmese ethnic minority group Rohingya.

Malaysian Deputy Minister of Health Hilmi Yahaya said on May 25 that Malaysia would conduct medical tests on the Rohingya migrants upon arrival to ensure the safety of Malaysian citizens.-VNA
