YANGON - Myanmar authorities lifted the house arrest of opposition leader Aung San Suu Kyi on Tuesday, her lawyer said, but she remained in detention while her trial continues.

The Nobel Peace laureate, whose house arrest was due to expire on Wednesday after six years in detention, is accused of violating the terms of the order by allowing an American intruder to stay in her home in early May.

The house arrest has been lifted, but she is still under detention. I don't know whether to be happy or sorry, Nyan Win, one of her lawyers, told reporters after Tuesday's court session.

He said Police Brigadier General Myint Thein read the order to Suu Kyi at her prison house in Yangon's notorious Central Insein Prison.

Suu Kyi, who has spent more than 13 of the past 19 years under some form of detention, is widely expected to be found guilty and faces up to five years in prison.

Western governments have denounced the trial as charade to keep the charismatic National League for Democracy (NLD) leader in detention during elections next year.
