Moscow - Around 1 000 nationalist demonstrators clashed with police in Moscow late on Sunday in protests against the killing of a Russian allegedly by a migrant, a media report said.
Police arrested at least 380 people, the Interfax news agency reported, citing the authorities.
The demonstrators were protesting about the death of a Russian who was stabbed to death in the Russian capital last week. Police said the perpetrator could have been a migrant worker from Central Asia or the Caucasus.
Rioters stormed a market run by migrants, and smashed the windows of a shopping centre. They also threw bottles, stones and rubbish bins at police. There were reportedly injuries.
Police were on duty late in the evening because of continuing clashes. Interior Minister Vladimir Kolokoltsev ordered a clampdown in a meeting with police chief Anatoly Yakunin. Kolokoltsev also called for the murder case to be wrapped up quickly.
The 25-year-old Russian killed last week was allegedly stabbed when he tried to protect his girlfriend.
There have been previous clashes between nationalists and migrants.
