Activities of the terrorists taking citizens hostages in Moscow Theater center might result in aggression against people of Caucasian nationality. Moscow Armenian national club chair Smbat Karakhanian has stated that in his interview with "Arminfo" agency. According to the reports received by the club via "hot line", already yesterday two aggression acts against people of the Caucasian nationality took place. Armenian residing in the Russian capital will also have many problems because of redoubling the passport control in Moscow. "Hot line" service received over 60 complaints only during 3 hours October 24 and this usually happens during a week. At present, Armenians need legal and psychological help, but Smbat Karakhanian worries that soon there will be calls from Armenians suffering violence.
