MOSCOW, Dec. 5 (Xinhuanet) -- At least 25 people were killed and more than 60 others injured Friday in a suicide bomb explosion which ripped through a commuter train in southern Russia, the Russian Em ergency Situations Ministry said.

    The blast took place in the station of Kislovodsk, near the war-wracked region of Chechnya, around 8 a.m. (0500 GMT) and destroyed the second car of the train.

    A bomb, which was placed beneath or in the second car, was detonated by an unidentified woman, Itar-Tass quoted the Interior Ministry as saying.

    Aid teams and rescue workers from Kislovodsk and Stavropol were working at the scene, trying to pull the victims out of the wreckage.

    The train was heading for Mineralnye Vody from Kislovodsk. The explosion occurred just as the train pulled out of the station of Kislovodsk.

    In recent months, Russia has been hit by a series of bombings and suicide attacks. The government usually blames the attacks on rebels from Chechnya. Enditem
