An explosion at a military academy in St. Petersburg that injured four students is being investigated as an attempted murder.
The Investigative Committee said on April 2, hours after the explosion at the Mozhaisky Academy, that the blast was being investigated as “an attempted premeditated murder of two or more persons using a…dangerous method.”
The statement said the blast occurred when an “unidentified coverless object” — apparently not a grenade or hard-shelled bomb — exploded.
It did not name any potential suspect.
The Interfax news agency cited an unidentified official close to the investigation as saying the authorities believe that a cadet. a teacher, or a staff member with access to the building could have been behind the blast.
