A report by human rights researchers at Harvard Law School has found that military activities carried out by Myanmar's powerful Minister of Home Affairs when the country was still under dictatorship could constitute war crimes.

The report released Friday says there is evidence that Ko Ko and two high-ranking colleagues were responsible for the executions, torture and enslavement of civilians by government troops during an offensive against ethnic rebels.

The researchers said they spent three years collecting information about the government's 2005-2006 counterinsurgency efforts in Karen state along the country's eastern border.

The Harvard findings come just before U.S. President Barack Obama and other world leaders attend an Asian summit meeting in Myanmar next week.

The government responded by saying much of what happens during times of conflict is unavoidable.
