With just ten days to go before the start of the Sochi Games, the Olympic torch is in the Caucasus region.

It was carried through Chechenya on Tuesday after making its way through the troubled region of Ingushetia.

On Monday, the torch passed through Dagestan, a region which has become the centre of an Islamic insurgency. Two militants from there have apparently claimed responsibility for a double suicide blast last month in Volgograd which left 34 people dead.

As a result Russian authorities are expected to mount the biggest security operation ever staged at a winter games.
