On 30 May, while travelling in Upper Myanmar, leaders and supporters of the National League for Democracy (NLD), the main opposition party, including General Secretary Daw Aung San Suu Kyi, were attacked by pro-government supporters. At least four people were killed and scores of government critics were arrested. Many of those arrested after 30 May were sentenced to long terms of imprisonment. Discussions between the State Peace and Development Council (SPDC), the military government, and Daw Aung San Suu Kyi did not progress during the year. Ethnic minority civilians continued to suffer extensive human rights violations, including forced labour, in SPDC counterinsurgency operations in parts of the Shan, Kayin, Kayah, and Mon States.
