More than 700 people in Rangoon have signed a petition this week calling for the release of opposition leader Aung San Suu Kyi and other political prisoners in military-ruled Burma.

U Lwin, spokesman for Burma’s main opposition party, the National League for Democracy, or NLD, said that as of yesterday about 600 party members and 100 others had signed the petition, which calls for the release of all political prisoners, including Suu Kyi and party chairman Tin Oo. The two have been confined to their homes for more than a year. The petition also called on the junta to reopen all NLD offices throughout the country.

The campaign began on July 19, at the 57th Martyrs Day commemoration at the party’s headquarters in Rangoon. In the following days, party members in Mandalay and Sagaing divisions signed the petition. Petitions are placed at temporary party offices and at the homes of elected NLD representatives.

Military authorities are generally quick to clamp down on such activities but have made no arrests so far.

Suu Kyi and Tin Oo were detained during the May 30 attack on the opposition’s motorcade in Depayin in northern Burma. The attack killed dozens, perhaps hundreds of opposition supporters. The junta closed the party’s offices after the attack.
