At least two protesters and one police officer have been killed after authorities clashed with demonstrators demanding greater autonomy in southern Nepal.
The violence began Thursday, when police tried to break up a group of protesters who were blocking a main road in Chitwan district, south of Nepal's capital, Kathmandu.
Officials say the demonstration turned violent and police opened fire to disperse the crowd. Two protesters were killed.
Officials say protesters attacked and killed a police officer Friday, despite a curfew in the area.
United Nations officials in Nepal have called on all sides to exercise restraint and have voiced concerns about the use of lethal force by police.
The ethnic Tharu protesters are demanding they be given greater rights, including self-government.
