An official says police in Nepal have clashed with protesters who were violently enforcing a general strike and detained at least 52.
Police spokesman Binod Singh says the protesters attacked and burned at least two dozen vehicles that were defying Sunday's general strike called by the Nepal Federation of Indigenous Nationalities.
The group called for businesses to close and vehicles to stay off the streets to support their demand that states proposed in the new constitution be determined on the basis of ethnic groups.
The Federation of Nepalese Journalists said it had reports that the protesters also attacked journalists.
Most markets and shops remained closed and highways were deserted Sunday. Singh said security has been stepped up.
