MOSCOW, May 31 (Xinhua) -- The Georgian Foreign Ministry Saturday denounced Russia for sending railroad troops to Abkhazia to help rebuild its railroad infrastructure, accusing Russia of planning to invade the breakaway region, RIA Novosti news agency reported.

　　"There is no need to send troops to rebuild railroads, unless the preparation for military intervention is under way," Georgia's Deputy Foreign Minister Grigol Vashadze was quoted as saying in a news briefing in Tbilisi.

　　Earlier in the day, the Russian Defense Ministry said the restoration of the Abkhazian transport infrastructure has been started. "The personnel and machinery of the Russian Railway Troops (without armaments) are taking part in this work," the ministry said.

　　However, Vashadze protested against the Russian statement, saying Moscow had not consulted with Tbilisi on the subject.

　　"We consider this move as another aggressive step against territorial integrity of Georgia," Vashadze said. "There is no doubt that Russia is building up military infrastructure (in Abkhazia) in preparation for military intervention."

　　Russian Ambassador to Georgia Vyacheslav Kovalenko will be summoned to the country's foreign ministry over the incident and an official protest note will be presented, the diplomat said.

　　Georgia's breakaway regions of Abkhazia and South Ossetia have long been a source of tensions between Russia and Georgia.

　　Bilateral relations have drastically deteriorated since Russia's former president Vladimir Putin ordered the government to render assistance to the two self-proclaimed republics in mid-April.
