There was an explosion at the OBI hypermarket in the "Mega Khimki" shopping center in Moscow.
APA reports with reference to TASS that a strong fire broke out after the explosion and the structure of the building collapsed.
The fire covers an area of 5 thousand square meters.
It is likely that the fire started due to a short circuit in the electrical wiring in the OBI store, and then spread over a wide area as a result of the explosion.
Fire brigades were called to the scene.
