Hundreds of people, including more than 200 members of political parties and young activists, were arrested for political reasons. Ten others were known to have been sentenced to long terms of imprisonment after unfair trials. At least 1,500 political prisoners arrested in previous years, including more than 100 prisoners of conscience and hundreds of possible prisoners of conscience, remained in prison. Daw Aung San Suu Kyi and other leaders of the National League for Democracy (NLD) were placed under de facto house arrest after being prevented by the military from travelling outside Yangon to visit other NLD members. Prison conditions constituted cruel, inhuman or degrading treatment, and torture of political prisoners was reported. The military continued to seize ethnic minority civilians for forced labour duties and to kill members of ethnic minorities during counter-insurgency operations in the Shan, Kayah, and Kayin states. Five people were sentenced to death in 2000 for drug trafficking.
