A state-run newspaper says Myanmar's de facto leader Aung San Suu Kyi has called the military's investigation into the deaths of Rohingya Muslims found in a mass grave a "positive indication."

Saturday's report says Suu Kyi said: "It is a positive indication that we are taking the steps to be responsible." She added: "I believe our investigation will prevent such things from happening again."

Suu Kyi made the comments Friday during a joint news conference with Japan's foreign minister. Suu Kyi is Myanmar's foreign minister as well as the government's de facto leader.

On Wednesday the military acknowledged that security forces and villagers were responsible for the deaths of 10 people found in a mass grave in December. It said the 10 were "terrorists" who threatened villagers.
