Russia 'starts Georgia pull-out'

Russia says its troops have started pulling back from a "buffer zone" around Georgia's breakaway region of South Ossetia.

A BBC correspondent in the area said he saw Russian forces dismantling and leaving one checkpoint they had set up.

Moscow must pull its troops from areas around South Ossetia and Abkhazia - another breakaway region in Georgia - by Friday under a ceasefire deal.

Russia has kept troops there since ousting Georgian forces in August.
