Myanmar’s junta has executed four prisoners, including a former MP from former civilian leader Aung San Suu Kyi’s party, state media reported on Monday, as the death penalty has been out of practice for decades.

The convicts, including an active pro-democracy activist, had been charged with “brutal and inhumane acts of terror”, according to Global New Light of Myanmar.

According to the official newspaper, the executions followed “prison procedures”, without specifying how or when they were carried out.

More than 15,000 detainees since the coup

Phyo Zeya Thaw, a former MP from Aung San Suu Kyi’s National League for Democracy party, was arrested in November and sentenced to death in January for violating the anti-terrorism law.

The other two prisoners executed are two men accused of killing a woman they suspected of being an informer for the junta. The ruling army continues a bloody crackdown on its opponents with more than 2,000 civilians killed and more than 15,000 arrested since the coup, according to a local NGO.

He also faces charges of genocide against the Rohingya. In 2017, more than 740,000 members of this Muslim minority found refuge in makeshift camps in Bangladesh to escape abuse by the military.
