The junta said on June 3 it would execute a former lawmaker from Aung San Suu Kyi's party and a prominent democracy activist, both convicted of terrorism, in what would be the country's first judicial executions since 1990.

Four people, including former MP Phyo Zeya Thaw and democracy activist Ko Jimmy, "who were sentenced to death will be hanged according to prison procedures", junta spokesman Zaw Min Tun told AFP then.

Nicholas Koumjian, head of the UN's Independent Investigative Mechanism for Myanmar, said he was following this case closely.

"The available information strongly suggests that under international law, fundamental rights of the convicted persons were blatantly violated in these proceedings," Koumjian said of the trials, which were closed to the public.

"Imposing a death sentence, or even a period of detention, on the basis of proceedings that do not satisfy the basic requirements of a fair trial may constitute one or more crimes against humanity or war crimes," he added.

The junta has sentenced dozens of anticoup activists to death as part of its crackdown on dissent after seizing power last year, but Myanmar has not carried out an execution for decades.
