Security tight after Russia blasts
Thousands of police officers and paramilitary personnel are on duty in the Russian city of Volgograd following two suicide bombings that killed 33 people and raised fears of a terrorist campaign ahead of the Winter Olympics.
In the wake of Sunday's bombing at the city's main railway station and Monday's blast on a trolleybus, police reinforcements and interior ministry troops have been sent into the city, regional police official Andrei Pilipchuk said. More than 5,200 security forces personnel have been deployed, he added.
Meanwhile the Russian emergencies ministry said two more victims died on Tuesday, raising the toll to 33 - 18 from the station bombing and 15 from the bus.
