A fire at the Russian Defense Ministry's Research Institute in the city of Tver, 180 kilometers northwest of Moscow, has killed six people.
The Tver regional government said on April 21 that 27 people sustained injuries, mostly after they jumped from windows of the three-story building to save their lives.
Thirteen people remain in hospitals, while others left medical institutions after receiving first aid, the regional government said in a statement.
The fire started on the second floor and covered some 1,000 square meters of the building, which houses the Central Research Institute of the Russian Aerospace Defense Forces.
According to preliminary investigations, the fire might have been caused by the malfunction of outdated electrical wiring in the old building.
