BBC News: 8 March 2013 Burmese opposition party, the National League for Democracy, is holding its first party congress since it was formed more than 20 years ago. Delegates from across the country are gathering in Rangoon to set out new policies and to select new members for its ageing leadership. Meanwhile, the Burmese president Thein Sein is finishing his trip across Europe and will return home to a country whose recent reforms have been rewarded by the lifting of sanctions, but where ethnic populations are suffering violent assaults. Troops continued a raid on rebels in Kachin state in the east over recent months, despite the president's orders to cease. And in the western Rakhine state, tens of thousands of Rohingya Muslims have been displaced amid clashes with Rakhine Buddhists, violence in which some say the state is complicit.
