 Russian Investigation Committee spokesman Vladimir Markin said the fresh explosion could also be a terror attack, resembling the Sunday blast in the city's railway station that left at least 16 dead and more than 40 injured. A criminal case under the act of terrorism and illegal turnover of explosives has been opened.

The Emergency Situations Ministry has sent a plane with medical modules onboard to attend the victims of the new explosion.
