Russian warships had arrived at Georgian Black Sea coast to prevent weapons from landing by sea, Interfax news agency quoted a Russian navy source as saying Sunday.
"The crews were assigned the task to not allow arms and military hardware supplies to reach Georgia by sea," the source told Interfax.
The Black Sea Fleet comprises missile cruiser Moskva, patrol boat Smetlivy, three large amphibious ships and logistics ships, the source said.
Meanwhile, the Abkhaz law enforcement agencies confirmed that several Georgian warships attempted on Saturday to approach the coast of Abkhazia. But the attempts were curbed by ships of the Russian Black Sea Fleet.
Abkhazia's armed forces conducted an operation to force Georgian troops out of the upper part of the Kodori gorge on Saturday. Georgian President Mikhail Saakashvili claimed that his country had defeated all attacks on the gorge.
An Interfax source said a sea blockade of Georgia will help avoid an escalation of combat operations in Abkhazia.
