St Petersburg, Dec 17 (AP) A Russian warship under construction at a shipyard in St Petersburg caught fire Friday, leaving at least three workers injured.

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