At least ten people lost their lives in a second deadly bombing in as many days in the Russian city of Volgograd.

A trolleybus was the target of the latest attack on Monday.

The blast came a day after a suicide bomber killed at least 17 people at the city's main railway station.

There was no immediate claim of responsibility for either of the attacks in which dozens were also wounded.

But the attacks have come less than two months before Russia hosts the Winter Olympics in the Black Sea resort of Sochi.

Insurgents who want an Islamic state in Southern Russia issued a web posting in July urging militants to use maximum force to stop the games taking place.
