MOSCOW, July 17. /ITAR-TASS/. Bodies of all casualties recovered after the tragic metro train crash in the Russian capital on Tuesday have been identified, an unnamed police source told ITAR-TASS on Thursday.

“All 22 people killed (in the crash) have been identified,” the source said. “Twenty of them were identified yesterday and two others today. The identification procedure has been completed.”

The tragic accident took place at 8:39 a.m. Moscow time (4:39 UTC) on Tuesday on the stretch of the west-bound "blue" line of the Russian capital’s metro network between the Park Podedy and Slavyansky Bulvar stations.

A rapidly moving train crashed entrapping all of its passengers in the underground tunnel after three of its cars derailed due to reasons that investigators have yet to establish.

Twenty people were killed on the scene of the incident. Two hours after the crash a woman died in a hospital and a young man died the next also in a hospital.

Georgy Glukhov, the head of the Moscow health department, said a total of 148 people requested medical assistance after the accident. Most of them were hospitalized with some of them sustaining aggravated injuries.

Moscow Mayor Sergei Sobyanin declared Wednesday the day of mourning in the Russian capital.
