Yangon - Myanmar's junta has dropped its guard over opposition leader Aung San Suu Kyi's compound in Yangon since her house detention officially ended on May 27, but she has meanwhile been transferred to Insein Prison, opposition sources said Monday.

"Daw (Mrs) Aung San Suu Kyi's house is already free from control by the authorities," Nyan Win, one of Suu Kyi's lawyers, said.

Suu Kyi, currently a resident at Yangon's notorious Insein Prison, has assigned two men to take care of her family compound in her absence, said Nyan Win, who is also the spokesman for the National League for Democracy (NLD) opposition party which Suu Kyi leads.

Suu Kyi spent six years under detention and near complete isolation in her family's lakeside home before being transferred to Insein Prison on May 9 to stand trial for breaking the terms of her incarceration.

On May 3, US national John William Yettaw, a 53-year-old Mormon, swam to Suu Kyi's house-cum-prison on Inya Lake, staying there until the night of May 5, when he swam away and was arrested.

Suu Kyi, whose detention term ended May 27, faces another three-to-five years in prison if found guilty of colluding in Yettaw's unauthorized visit.

Her trial, being held at a special court set up in Insein Prison, will resume on June 26.

The Nobel peace prize laureate's latest legal travails have sparked international condemnation and expressions of concern by western governments and even from some of Myanmar's close allies in South-East Asia.

In the latest protest on Monday, 100 well-known former political prisoners added their voices to calls for Suu Kyi's immediate release.

"Aung San Suu Kyi's continued detention shames Asia," said former Korean president Kim Dae-jung, one of the prominent former political prisoners to sign a petition demanding Suu Kyi's freedom before her 64th birthday on June 19.

"ASEAN cannot continue its policy of non-intervention. It's time to work together for regional stability and prosperity," said Anwar Ibrahim, Malaysia's prominent opposition leader who spent several years in jail under the rule of former premier Mahathir Muhammad.

The 100 former political prisoners also called on the United Nations Security Council to establish a global arms embargo on Myanmar.(dpa)
