At least 10 people were killed and more than 100 people injured, many of them seriously, when a Moscow subway train derailed during the busy morning rush hour, Panorama.am reported citing RFE/RL.

A spokesman for the Emergencies Ministry said a power surge caused the train to stall and several cars to derail between the Slaviansky Boulevard and Park Pobedy stations.

Russian Emergency Situations Minister Aleksandr Drobyshevsky said eight helicopters from his ministry were helping evacuate the injured from the scene, in addition to dozens of ambulances that had already arrived.

The accident is one of the most serious to hit the Moscow subway, which carries about 9 million passengers per day.

The RA embassy in Russia said there are no Armenian citizens among the accident victims.

According to the latest reports, the death toll reached 21.
