Two senior commanders of the Karen National Defence Organisation (KNDO) have admitted that security forces under their control detained and later killed 25 men in June in its territory near Myanmar’s border with Thailand, Al Jazeera reported quoting Fortify Rights.

General Ner Dah Bo Mya and Lieutenant Saw Ba Wah, who have been suspended from their posts by the Karen National Union (KNU), told Fortify Rights that their men were responsible.

Fortify Rights said the KNU had confirmed they would cooperate with international investigators and share evidence of the killing and other crimes, as well as conducting its own investigation into the atrocities. The killing amounts to a war crime. Fortify Rights said on Tuesday.
