Myanmar has begun releasing the first of about 100 political prisoners days before democracy champion Aung San Suu Kyi's party forms government.
The move by the outgoing administration of President Thein Sein comes after US Assistant Secretary of State Antony Blinken urged Myanmar to free all political prisoners during a visit on Monday.
"So far, 18 political prisoners were released from Insein Prison. They will release a total of 21 people today," an official at Yangon's Insein prison said on Friday.
Insein is one of Myanmar's largest prisons. It is used for jailing political prisoners and is notorious for its poor conditions and treatment of inmates.
A senior official from the Home Ministry told Reuters more than 100 prisoners would be freed from various detention centres across Myanmar.
Another from the President's Office said the political inmates were being released as a commemoration of the World Buddhist Peace Conference that starts in Myanmar on Friday.
"Most of them were arrested for staging protests. As far as I know, there will be 101 political prisoners who will be released in the coming days," said Bo Kyi, Joint Secretary of political prisoner watchdog the Assistance Association for Political Prisoners.
Myanmar's incarceration of more than 2000 journalists, activists, politicians and even comedians during decades of military rule was a key factor behind Western sanctions.
Hundreds were released by Thein Sein's semi-civilian government, which replaced the junta in 2011 and embarked on a series of political and economic reforms.
However, human rights groups had complained that many were still in jail. In December, there were 129 political prisoners incarcerated in Myanmar and 408 activists were awaiting trial, according to AAPP's website.
A new parliament dominated by Nobel peace laureate Suu Kyi's National League for Democracy will sit for the first time on February 1.
