Myanmar's embattled junta government on Saturday said it would release almost 6,000 prisoners as part of an annual amnesty to mark the country's independence day.

The military has arrested thousands of protesters and activists since its February 2021 coup that ended Myanmar's brief democratic experiment and plunged the nation into turmoil.

More than 5,800 prisoners — including 180 foreigners — will be freed, the junta said in a statement on Saturday, when the country marks 77 years of independence from British colonial rule.

It did not give details of what the prisoners had been convicted of or the nationalities of the foreign detainees who were set to be deported on release.

The military said it ordered the pardons "on humanitarian and compassionate grounds".

The junta also announced that 144 people who had been sentenced to life in prison would have their sentences commuted to 15 years.

Myanmar frequently grants amnesty to thousands of prisoners to commemorate holidays or Buddhist festivals.

Last year, the junta announced the release of more than 9,000 prisoners to mark independence day.

The annual independence day ceremony held in the heavily guarded capital Naypyidaw on Saturday morning saw around 500 government and military attendees.

A speech by junta chief Min Aung Hlaing — who was not present at the event — was delivered by deputy army chief Soe Win.

Soe Win reiterated the junta's call to dozens of ethnic minority armed groups that have been fighting it for the last four years to put down arms and "resolve the political issue through peaceful means."

He repeated a military pledge to hold delayed democratic elections and called for national unity.
