Two Russian navy ships are completing preparations to sail to Syria with a unit of marines on a mission to protect Russian citizens and the nation's base there, a news report said Monday. The deployment appears to reflect Moscow's growing concern about Syrian President Bashar Assad's future.
The Interfax news agency quoted an unidentified Russian navy official as saying that the two amphibious landing vessels, Nikolai Filchenkov and Caesar Kunikov, will be heading shortly to the Syrian port of Tartus, but didn't give a precise date.
The official said the ships will carry an unspecified number of marines to protect Russians in Syria and evacuate some equipment from Tartus, if necessary.
Each ship is capable of carrying up to 300 marines and a dozen tanks, according to Russian media reports. That would make it the largest known Russian troop deployment to Syria, signaling that Moscow is becoming increasingly uneasy about Syria's slide toward civil war.
Interfax also quoted a deputy Russian air force chief as saying that Russia will give the necessary protection to its citizens in Syria.
"We must protect our citizens," Maj.-Gen. Vladimir Gradusov was quoted as saying. "We won't abandon the Russians and will evacuate them from the conflict zone, if necessary."
Asked whether the air force would provide air support for the navy squadron, Gradusov said they will act on orders.
The Defense Ministry had no immediate comment, and an official at the Black Sea fleet declined to comment.
Tartus is Russia's only naval base outside the former Soviet Union, serving Russian navy ships on missions to the Mediterranean and hosting an unspecified number of military personnel.
Russian officials have said that other Russian navy ships that have called at Tartus this year also had marines on board, but it has remained unclear whether they rotated the troops at Tartus or simply protected the ships during their mission and returned home.
Russia also has an unspecified number of military advisers teaching Syrians how to use Russian weapons, which make up the bulk of Syrian arsenals.
Syria is Russia's last remaining ally in the Middle East, and has been a major customer of Soviet and Russian weapons industries for the last four decades, acquiring billions of dollars worth of combat jets, helicopters, missiles, armored vehicles and other military gear.
Russia has shielded Assad's regime from international sanctions over its violent crackdown on protests. Moscow also has continued to provide Syria with arms, despite Western calls for a halt in supplies.
U.S. Secretary of State Hillary Rodham Clinton issued a harsh reprimand of Russia last week, when she said that Moscow "dramatically" escalated the crisis in Syria by sending attack helicopters there. The State Department acknowledged later the helicopters she accused Moscow of sending were actually refurbished ones already owned by the Assad regime, but Russia was clearly annoyed, and the spat further fueled tensions ahead of President Barack Obama's meeting with Russian President Vladimir Putin on the sidelines of the G-20 summit in Mexico on Monday.
Opposition groups say more than 14,000 people have been killed since the Syrian uprising began in March 2011 with mostly peaceful protests against Assad's autocratic regime. But a ferocious government crackdown led many to take up arms, and the conflict is now an armed insurgency.
Russia has criticized Assad for slow reforms and heavy-handed use of force, but has strongly opposed any sanctions or foreign interference in Syrian affairs.
