MOSCOW, Aug. 8 — The Republic of Georgia presented what it called a mounting body of evidence today that a Russian warplane had entered deep into its airspace and fired an air-to-ground missile. It said it was seeking a special session of the United Nations Security Council to address the incident.

No one was injured by the missile, which was fired Monday evening and struck near Tsitelubani, a village about 30 miles from Tbilisi, the Georgian capital. The missile broke apart at impact, but did not explode.

The strike, the second mysterious raid with sophisticated, Russian-made weapons on Georgian soil this year, inflamed tensions anew between the two countries. Russia has denied any role, and suggested that Georgia attacked itself. Like Georgia, it has said it wants a comprehensive investigation of the incident.

But with Georgia marshaling its evidence and its foreign minister, Gela Bezhuashvili, rallying international support, the missile strike seemed to pose problems for Russian diplomacy in the turbulent Caucasus. It also raised new questions about Russia’s activities in the region and the truthfulness of its statements.
