In the past two days dozens have been killed in Russia. The latest killed 10 when an explosion ripped through a trolleybus in the second deadly blast in the Russian city of Volgograd, according to the Interfax news agency.

These explosions come a day after a suicide bomber killed at least 17 people in the main railway station of the southern Russian city.

The countdown is on with 40 days before Russia holds the Winter Olympics in the Black Sea resort city of Sochi.
