Russian forces battle Georgians

Russian forces are locked in fierce clashes with Georgia inside its breakaway South Ossetia region, reports say, amid fears of all-out war.

Moscow sent armoured units across the border after Georgia moved against Russian-backed separatists.

Russia says 12 of its soldiers are dead, and separatists estimate that 1,400 civilians have died.

Georgia accuses Russia of waging war, and says it has suffered heavy losses in bombing raids which Russia denies.

Russian tanks have reportedly reached the northern suburbs of the regional capital, Tskhinvali, and there were conflicting claims about who was in control of the city.

"Now our peacekeepers are waging a fierce battle with regular forces from the Georgian army in the southern region of Tskhinvali," a military official was quoted as saying by the Russian news agency, Interfax.

Georgian forces had moved on Thursday night to regain control of the province, which has had de facto independence since a war against Georgia that ended in 1992.

Georgian President Mikhail Saakashvili said Russia was making war on his country.

He told the BBC: "Our troops are attacked by thousands of troops coming in from Russia."

He said Georgia had shot down several Russian planes and accused Moscow of bombing Georgian air bases and towns, resulting in the death of 30 military personnel and civilians.

Despite denials from Moscow, the Russian air force has been carrying out air raids in South Ossetia and Georgia itself, says the BBC's Richard Galpin, in Gori, eastern Georgia.
