KATMANDU, Nepal - A bomb exploded in a busy market area in a southern Nepal town where a political rally was being held, killing at least four people and wounding 14 others, police said.
The explosion occurred in Janakpur during Monday morning rush hour, police said. People had gathered in the area for a political rally to demand a separate state in a new constitution being drafted by the country's Constituent Assembly.
According to witnesses, the bomb was hidden in a red motorcycle parked next to the rally, police said.
Police detained one person for questioning. A little-known group calling itself Janatantrik Terai Mukti Morcha claimed responsibility for the bombing.
The town is about 200 kilometres (125 miles) southeast of Nepal's capital, Kathmandu.
