More than one hundred Moscow commuters were still being treated for their injuries in hospital on Monday morning, just short of a week after a fatal metro derailment killed at least 23 people.
Head of Moscow's Health Department, Georgy Golukhov, told Interfax Monday 117 people were still in hospital — fifteen of whom were in critical condition, and at least four of whom were being kept on artificial respiration in intensive care.
Three metro cars skidded off the rails during morning rush hour last Tuesday between the Slavyansky Bulvar and Park Pobedy metro stations on the Moscow Metro's Dark Blue Line, killing at least 23 people and injuring more than 160 others.
Russia's Investigative Committee said it believed the accident was caused by a faulty railway switch that had been fastened using wiring that could not withstand the passage of trains.
Two rail technicians responsible for overseeing work on the tracks had been detained for interrogation in relation to the accident as of Monday morning.
