Russia has declared a "day of mourning" as death toll from an underground train derailment in Moscow rises to 21. "Wednesday will be a day of mourning in Moscow, given the scope of the tragedy," Moscow Mayor Sergei Sobyanin said on Tuesday. According to the Russian Emergencies Ministry, the accident occurred as a train going from the city center halted abruptly between the Park Pobedy and Slavyansky Bulvar stations early on Tuesday morning. The incident derailed three train cars. The ministry also believes that the accident was a result of a sudden sharp decline in the voltage, but Moscow's electricity company denies any fall in the rails voltage. The Russian Health Ministry announced that around 129 people were injured, 49 of whom are in critical condition. The cause of the accident is still under investigation by Russian authorities. The incident remains one of the most serious accidents to hit Moscow's metro system in recent years.
