Russian race unrest

Russian police detained a migrant worker suspected of killing an ethnic Russia and stepped up security in Moscow on Tuesday to try prevent a repeat of the race riots that were unleashed by the man's death.

Advocacy groups warned migrants from ex-Soviet states of Central Asia and the Caucasus of a high risk of violence as crowds of Muslims celebrated the Islamic holiday of Eid al-Adha, and a heavy police presence was seen in the capital. (Reuters)
