A bomb blast tore through a bus in the southern Russian city of Volgograd on Monday, authorities said, killing at least five people in the deadliest such attack outside Russia's volatile North Caucasus region in nearly three years.
The explosion also wounded 17 people, seven of whom were in grave condition, a spokesman for the local investigators said.
The investigators suspect a female suicide bomber was responsible for a bombing, the Interfax news agency reported.
Interfax said identity documents belonging to the suspected bomber were found near the site.
Volgograd is a city of around one million people that lies 900 km (560 miles) southeast of Moscow and a few hundred kilometres north of the North Caucasus and Black Sea resort city of Sochi, where Russia will host the 2014 Winter Olympics.
President Vladimir Putin has staked his reputation on the Games and ordered authorities to boost security in the North Caucasus.Last Mod: 21 Ekim 2013, 16:57
