YANGON, Myanmar -Myanmar’s main pro-democracy party launched a nationwide signature campaign Thursday to press for the immediate release of its detained leader, Aung San Suu Kyi, and other political detainees.

The petition campaign was launched Thursday in Yangon at the headquarters of Suu Kyi’s National League for Democracy party during a Union Day celebration attended by nearly 300 party members.

“The campaign is meant to show the ruling military junta and the international community the solidarity of the people and support of the people,” party spokesman Nyan Win said. He said the party had not yet decided what to do with the collected signatures.

The party held a similar campaign in 2004 with no evident results.

Human rights groups say Myanmar holds more than 2,100 political prisoners, up sharply from nearly 1,200 before pro-democracy protests led by Buddhist monks were crushed in 2007.
