Georgian forces have shot down two Russian planes as the two sides look close to all-out war.

A fighter jet and bomber have been attacked in the fight for South Ossetia.

Georgia is trying to take back the province which broke away during the 1990s.

Russian tanks and troops want to stop the operation - Russian jets have carried out a series of strikes on military targets in the central Georgian city of Gori, close to the breakaway region of South Ossetia.

Most of the targets seem to have been military bases, but Georgian officials said a number of civilians had been killed in residential buildings.

Georgian president Mikhail Saakshavili insists Moscow is the aggressor: 'It's about Russia trying to intrude and basically undermine Georgia. But basically, yes, we would like to have a ceasefire, separation of forces, and direct dialogue with the Russians.'

Russian Foreign Minister Sergei Lavrov said about 1,500 people had so far been killed.
