A new human rights report has found gaps in the investigation and possible obstruction of justice involving Malaysia's 2015 discovery of mass graves believed to be of Rohingya Muslims and Bangladeshis held in trafficking camps in a jungle area on its border with Thailand.

The report, prepared by the Human Rights Commission of Malaysia and Fortify Rights, comes after Malaysia's new government in January formed a royal commission of inquiry into the tragedy at Wang Kelian in northern Perlis state that shocked the nation amid allegations of a cover-up.

A commissioner with the Human Rights Commission, Jerald Joseph, said Wednesday there was "fresh political will in Malaysia to right these wrongs" and ensure justice for all trafficking victims.
