The BBC reports:

Georgia has accused Russia of violating Georgian airspace for the second time in a month. The foreign ministry in Tbilisi said a Russian fighter jet flew 5km (3 miles) into Georgian territory on Tuesday. Moscow immediately denied the claim, saying Russian planes did not fly near the Georgian border on that day. Earlier this month, Georgia said a Russian plane had dropped a missile on Georgian territory, an accusation strongly denied by Russia. On Wednesday, Georgia's foreign ministry said in a statement that the Russian jet had crossed into the north-west of Georgia. It said the incursion had been tracked by the Georgian air defence system. Relations between the two former Soviet republics have been strained since a spy row last year.
