President Saakashvili says the Russian army controls around a third of Georgia, two days after both Moscow and Tbilisi signed up to a ceasefire. Tanks and troops deployed around three Georgian towns despite growing international pressure for the military to withdraw.

Prosecutors from Russia and South Ossetia said they were investigating claims of what they called Georgian “genocide” in the separatist region.

For many people who fled South Ossetia, there is an agonising decision to make: do they take the risk of returning home now, or wait until there is confirmation that a complete ceasefire is being respected. In one sanatorium in North Ossetia, more than 300 people have sought refuge.
