Russian media reports, quoting law-enforcement sources, said that the
explosion happened after a police officer tried to stop a suspicious
young woman near security gates installed to prevent guns and explosives
being taken inside the station. Security officials expressed hope that
the bomber would be soon identified.
Soldiers found an unexploded
grenade at the scene, Vladimir Markin, an investigative committee
spokesman, told the news agency RIA. He said the metal frames installed
at the entrances of all Russian railway stations and airports – a
security measure often ridiculed in the Russian media – had prevented
more casualties. A train from Moscow was due to arrive half an hour
after the explosion took place.
Volgograd, formerly Stalingrad, is
a railway hub on the route connecting European Russia with central
Asia. It acts as a gateway to the Caucasus, and is 600 miles from Sochi,
the Black Sea city where the Olympics are scheduled to start on 7
February. Russian authorities have insisted there will be no security
threats to the event, despite the city lying just west of the restive
North Caucasus region. In July Doku Umarov, leader of the remaining
Chechen jihadist groups, warned that militants would try
sabotage the Games.
