A Russian naval ship carrying out target practice off the Russian Baltic Sea coast accidentally rained shell fragments on a village near St. Petersburg, officials said Friday.

Nobody was injured when the fragments from shells fired by an anti-submarine ship in the Gulf of Finland fell on houses in the village of Zelyonaya Roshcha, close to the border with Finland, regional military prosecutor Igor Lebedev said. An investigation has begun, Lebedev said.

Russia's NTV television said that the ship fired its six-barrel anti-aircraft gun near the shore, and the exploding shells rained shards of metal on the village. It showed metal fragments several centimeters (inches) long which were spread all over the area.

"Some people thought that a war started," one villager, Yuri Mikhailov, was quoted as telling the RIA Novosti news agency. "It was like a hail of steel."
