Myanmar military says that several bodies have been found in suspicious circumstances in strife-torn Rakhine State, while vowing that any troops implicated in unlawful killings will be punished, state media reported Tuesday.

In a statement, the military said "several unidentified corpses" were found buried at a cemetery in Inn Din village of Maungtaw Township, following a tipoff.

Inn Din is the same place where international human rights organizations have reported that atrocities against Rohingya Muslims allegedly took place earlier this year.

The military said a detailed investigation is under way to uncover the truth behind the killings in the village in northern Rakhine.

It said the security forces operating in the area have been instructed to strictly adhere to the rules of engagement, and pledged that action would be taken against those who do not.

In September, Amnesty International released a report that mentioned at least five Rohingya villagers being killed by the security forces at Inn Din, citing accounts from residents among the more than 600,000 Rohingya who have fled across the border to Bangladesh since Aug. 25.

The village is situated between two of the more than 30 police posts that were attacked by Rohingya militants then, sparking a harsh crackdown by the security forces and local militias.

Meanwhile, a report released by Human Rights Watch on Tuesday accused the Myanmar military of "systematically" killing hundreds of Rohingya in another village in the same township on Aug. 30.

The 30-page report titled "Massacre by the River: Burmese Army Crimes against Humanity in Tula Toli," is based on the accounts of witnesses and survivors of the massacre interviewed in Bangladesh.

They said uniformed soldiers surrounded the village, separated the men from the women and children, systematically killed the men, and transferred the women and children from the river to nearby houses where they were often raped and killed.

Human Rights Watch said the accounts support allegations that "widespread and systematic" attacks by Myanmar's military on the long-persecuted, stateless Rohingya Muslim community since Aug. 25 "amount to crimes against humanity."
