Blast at St Petersburg academy caused by World War Two ammunition, military says

(Reuters) -Russia's military said on Friday that a blast that injured seven servicemen at a military academy in St. Petersburg was caused by the accidental detonation of World War Two-era ammunition, Interfax news agency reported.

Interfax news agency, quoting the Leningrad military district, said the servicemen were injured at the Budyonny Military Academy of the Signal Corps during a check of underground areas in St Petersburg, Russia's second largest city.

St Petersburg Governor Alexander Beglov said the blast was not linked to terrorism.
