Myanmar started releasing political prisoners on Wednesday as part of an amnesty announced by the government.
Reports say between 150 and 300 ‘prisoners of conscience’ have been freed.
Authorities have yet to give the exact figure.
Pro-democracy activist Aung San Suu Kyi welcomed the move. She was released from 15 years of house arrest last November and has since held talks with the government.
There are conflicting reports as to whether dissident Buddhist monk Shin Gambira is also among those to go free from jail.
Gambira played a prominent role in street marches in 2007 that were violently suppressed by the then-military junta.
Releasing political prisoners has long been a key demand by Western powers. They want the country formerly known as Burma to improve its human rights record before easing sanctions.
