Moscow/Tbilisi, Georgia - Russian aircraft carried out airstrikes overnight Friday against targets near Tbilisi, according to reports early Saturday from Georgia.

The conflict over Georgia's breakaway South Ossetia region raged on as the Georgian Air Force base at Vaziani was bombed, according to the Russian news agency Itar-Tass, citing the Georgian Interior Ministry.

There were no initial details about casualties or damage at the air base, about 20 kilometres south-east of the capital.

Attacks by air were also reported at a military base in Senaki in western Georgia and in Poti, a port on the Black Sea.

The Russian military in South Ossetia reported that Georgian troops had renewed artillery fire overnight into Tskhinvali, capital of the Russian-supported Caucasus province. The latest bombardment struck mostly in residential areas, the Russians alleged. (dpa)
