MOSCOW - Russia has delivered anti-ship cruise missiles to Syria, the Interfax news agency cited an unnamed military source as saying on Thursday.

"The contract was completely fulfilled, almost ahead of time," Interfax cited the source as saying of the deal, estimated at $300 million. The source did not say when the deliveries had taken place.

Defence Minister Anatoly Serdyukov said in February that Moscow was pressing ahead with the deal despite Israeli concerns, indicating the missiles might have been delivered earlier this year.

"This weapon allows coverage of the entire coastline of Syria from possible attack from the sea," Interfax quoted the source as saying.  

Earlier this week, Russian newspaper Izvestia reported that Russia planned to send its aircraft carrier and other ships to Syria.

Besides accounting for 7 percent of Russia's total of $10 billion in arms deliveries abroad in 2010, according to Moscow defence think-tank CAST, Syria also hosts a Russian naval maintenance facility.

Israel has voiced concerns over the contract for sale of the rockets, capable of hitting ships 300 km (190 miles) off Syria's coast. Hezbollah used a surface-to-air missile in the 2006 Israel-Lebanon War to hit the INS Hanit warship, killing four sailors.
