10 killed in explosion at Russian train station

MOSCOW: An explosion ripped through a train station in the Russian city of Volgograd on Sunday, killing at least 10 people, Russian news agencies said.
The cause of the blast was not immediately clear. An attack by a female suicide bomber in the same Russian city on October 21 killed seven people.

It lies close to Russia’s North Caucasus, a strip of mostly Muslim provinces plagued by near-daily violence in a long-running Islamist insurgency. Insurgent leader Doku Umarov, a Chechen warlord, urged militants in a video posted online in July to use “maximum force” to prevent President Vladimir Putin staging the Olympics.

There was no immediate claim of responsibility after Sunday’s explosion.
