MOSCOW, December 8 (RIA Novosti) - One naval officer died in a fire on Russia's Baltic Fleet frigate the Neukrotimy (Indomitable) on Monday, a senior Navy official said.

"The body of an officer was discovered during a thorough search of the ship," Captain 1st Rank Igor Dygalo, an aide to the Russian Navy commander, said.

Earlier reports said no one had been hurt in the fire that broke out early on Monday on the frigate anchored at Baltiisk, the Baltic Fleet's main base.

A regional emergencies official said the fire was put out at 14:00 Moscow time (11:00 a.m. GMT).

He said five firefighting teams, including a special firefighting boat, had been involved in extinguishing the fire.

The Baltic Fleet press service said only insignificant damage had been caused to the vessel, while the cause of the fire had yet to be established by a special investigations commission.

Dygalo said the frigate, at the end of its operational life span, was due to be taken out of service, adding there had been no weapons on board the ship when the fire started.

The Krivak-2 Project-1135 Neukrotimy, built in 1978, was damaged in 2005, when a practice mine exploded during rehearsals for Russia's Navy Day, causing a 3-meter hole in the ship's hull and flooding the ship's engine room.
