Russian and foreign human-rights groups have raised concerns over what they say is the alarming spread of racist and xenophobic attitudes in Russia in recent years.
The latest in a string of attacks on foreigners with non-Slavic features occurred in the southern city of Rostov-on-Don March 9 when a Syrian student was beaten up.
The central Russian city of Voronezh alone has seen as many as seven racially motivated killings over the past six years, including the murder of a Peruvian student in October 2005.
On January 11, 2006, Moscow saw a shocking attack on a synagogue when a 20-year-old man stabbed nine people with a hunting knife.
