Russian troops have entered Georgia

Russian troops have entered Georgia from the breakaway region of Abkhazia, reaching the town of Senaki, officials from both Russia and Georgia say.
The Russian defence ministry said its troops had moved in to stop Georgia from attacking Russian forces in South Ossetia, another breakaway region.
As the fighting continued in south Ossetia, foreign envoys were pressing for a ceasefire in the conflict.
Each side accuses the other of carrying out atrocities in the region.
