Fire engulfs Russian warship under construction

At a shipyard in St. Petersburg, a Russian warship under construction caught fire on Friday. Local authorities said three workers were injured, with two of them requiring hospitalization.

The Provorny (Agile) corvette being built at the Northern Shipyard was completely engulfed by flames. Nearly 170 firefighters were taking part in efforts to extinguish the blaze that sent massive plumes of smoke over Russia's second-largest city.

An official panel has been created to investigate the cause of the fire. The corvette is the latest in a series of such ships built at the shipyard. It was set to be commissioned by the navy late next year.
