The United Nations report released on Monday, based on video footage and radar records, confirmed Georgia's earlier claims that on April 20 the Russian Air Force shot down a Georgian drone over Abkhazia. Russia's Defense Ministry has rejected the report.
Saakashvili said: "Today Georgia is in a complicated situation, because the army of a foreign state that we did not invite, and that we do not accept here at all, entered Georgia's territory. Yesterday the UN published a conclusion directly accusing the Russian Federation of an act of aggression against Georgia."
"It was confirmed that a Russian plane bombed Georgian territory. This is the first case when an international organization... has directly pointed at the Russian Federation over these actions," he told reporters in Tbilisi.
Authorities in the breakaway republic of Abkhazia say they have downed seven Georgian drones since March, but Tbilisi has officially confirmed the destruction of only one of them, on April 20.
In response to the UN report, Abkhaz Foreign Minister Sergei Shamba told RIA Novosti that the province could pull out of UN-brokered peace talks with Georgia.
Colonel Alexander Drobyshevsky, the head of the Russian Defense Ministry's press service, said: "No violation of the state border with Georgia, let alone the downing of an unmanned reconnaissance plane, took place."
He said Russian Air Force planes did not approach the Georgian border on April 20.
Relations between Russia and Georgia have been consistently strained since Saakashvili came to power in Georgia four years ago, being damaged by numerous disputes, most recently over Russia's moves to develop closer ties with Georgia's two breakaway regions.
Bilateral relations saw a new low in April when then president Vladimir Putin instructed the government to establish closer ties with Abkhazia and South Ossetia. Georgia accuses Russia of trying to annex the provinces, while Russian officials have said Tbilisi plans to invade Abkhazia.
The pro-Western Georgian leadership's plans to join NATO, and a series of blockade measures imposed on Georgia by Russia in 2006 have also presented major setbacks in ties between the countries in recent years.
