Explosion at military academy

Three people were injured in an explosion inside an elite military academy in Russia’s second-largest city, the country’s defence ministry has said.

The ministry said in a statement that an unidentified “object” went off early afternoon inside the prestigious Mozhaisky Academy in St Petersburg, which trains officers for the army’s missile defense unit. Three people suffered non-life-threatening injuries.

Authorities did not give other details. Several windows were shuttered on the second floor of the building, and dozens of cadets were being led out of the gated compound.
