A blast has rocked a building of Russian Aerospace Forces Academy in St. Petersburg, local emergency services said as cited by RIA Novosti news agency. At least four people are reported to have been injured.
The explosion inside an office building of the academy happened on Tuesday afternoon, Russian media reported. The cause of the blast was not immediately clear.
The institution, named after Russian aviation pioneer Alexander Mozhaysky, is a flagship educational institution which commissions officers for the Air Force and other branches of the Russian Armed Forces.
Four people were injured in the blast, Acting Governor of St. Petersburg Alexander Beglov has told reporters.
“We have three injured people and one with slight injuries,” Beglov said.
According to early reports, all individuals injured in the blast were officers.
Beglov said all services had operated promptly to deal with the aftermath of the blast. All communications were disconnected promptly. “People were evacuated, which is the most important thing, the head of the academy and everybody reacted the way they were supposed to,” the acting governor said.
An unidentified shell-less device went off at office premises of an administrative building of the academy at about 13:30 on Tuesday. No students were injured in the blast, other reports said.
According to a source from the North-Western Federal District’s emergency service, the explosion occurred in a lower storey of a building of the academy during the transportation of a dangerous object.
