Georgia accused Russia of downing the unmanned aircraft over its breakaway region on Sunday. Russia has denied the accusations.
"The flight taken by a reconnaissance aircraft, which could also be used to direct fire, is a violation of the Moscow agreement on the ceasefire of May 14, 1994, as well as relevant UN Security Council resolutions," the ministry said in a statement.
The ministry said the Moscow agreement states that there should be no armed forces in the security zone, while in line with the latest UN Security Council resolution 1808 adopted April 15, the sides should see to it that no unauthorized military activity be carried out in the area.
According to the Russian Defense Ministry and Abkhaz authorities, the Georgian drone entered the security zone from Georgia, flew through into Abkhaz territory, made a U-turn above the Ochamchira port and tried to return to Georgia via the security zone again.
"At 09.50 on April 20 it was shot down by Abkhaz air defense 20 km southwest of Gali. Part of the fragments fell onto the coast and the rest into the sea... The UN mission received a report from the Georgian Interior Ministry the same day in the evening, at about 19.00, and naturally was unable to notify the Abkhaz side. So the flight was unsanctioned military activity," the Russian ministry said.
The ministry said the fragments of the drone were showed to media, peacekeepers and UN representatives Monday, and that the drone was identified as an Israeli-made Hermes 450, the same model as one downed over Abkhazia March 18.
The commander of Russia's Air Force dismissed Tuesday Georgia's claims that a Russian MiG-29 fighter shot down the Georgian drone.
"Russia's Air Force has nothing to do with it," Col.-Gen. Alexander Zelin told journalists. "We don't fly beyond the state border, we fly over the territory of the Russian Federation."
The United Nations Security Council has scheduled a meeting for Wednesday at Georgia's request, to discuss the row between the two countries and Tbilisi's claims of Russian "aggression" in Abkhazia.
Georgia's state minister for Euro-Atlantic integration, Georgy Baramidze, was due on a visit to the United Kingdom Tuesday to discuss the situation in Abkhazia and South Ossetia, the minister's staff said.
Georgia is seeking to regain control of Abkhazia and South Ossetia which it lost in 1991 when the two republics broke away in conflicts following the breakup of the Soviet Union.
Georgia has reacted furiously to Russia's announcement Wednesday that it plans to strengthen its ties with South Ossetia and Abkhazia, which borders on Russia.
Ex-Soviet breakaway regions have stepped up their drive for independence since Kosovo's declaration of independence on February 17. Abkhazia and South Ossetia, along with Moldova's Transdnestr, have since asked Russia's parliament, the United Nations and other organizations to recognize their independence.
