Russia Fears More Attacks Prior to Sochi Winter Olympics
The deadly blast in the city of Volgograd may be just a warning that militant groups plan to step up attacks in Russia in the run-up to the Winter Olympics in the Black Sea resort city of Sochi next February, Russian experts fear.
A suspected female suicide bomber set off on Monday explosives on a bus in the southern Russian city of Volgograd, killing at least six people.
Officials believe the woman was from Dagestan in the North Caucasus and was the partner of an Islamist militant.
The blast, which happened just after 14:00 (10:00 GMT), also injured more than 30 people, some of them seriously.
An Islamist insurgency in the North Caucasus region has led to many attacks there in recent years.
According to preliminary information, the self-explosion was carried out by a 30-year-old Dagestani native, Naida Akhiyalova.
