Russian Police Detain Migrant Workers to Try to Calm Tension

Riots over killing of man blamed on a migrant

Police detained more than 1,000 migrant workers for several hours Monday in an effort to calm simmering ethnic tension in Moscow following a weekend riot triggered by the killing of a Russian man that residents blamed on a migrant.

The clashes were the most violent for several years in Moscow, where relations between ethnic Russians and migrants from the predominantly Muslim Caucasus region and the former Soviet states in Central Asia have long been strained.
