Moscow/Washington: Russia called on Friday for military-to-military cooperation with the United States to avert "unintended incidents" as it stages navy exercises off the coast of Syria, where U.S. officials believe Moscow is building up forces to protect President Bashar al-Assad.
The United States is using Syrian air space to lead a campaign of air strikes against Islamic State, and a greater Russian presence raises the prospect of the Cold War superpower foes encountering each other on the battlefield.
Both Moscow and Washington say their enemy is Islamic State, whose Islamist fighters control large parts of Syria and Iraq. But Russia supports the government of Assad in Syria, while the United States says his presence makes the situation worse.
In recent days, U.S. officials have described what they say is an increase of Russian equipment and manpower.
President Barack Obama said this would not change U.S. strategy in countering Islamic State fighters, which includes U.S. planes leading an international coalition in airstrikes in Syria.
"But we are going to be engaging Russia to let them know that you can`t continue to double-down on a strategy that is doomed to failure," he said at an event with military service members during a visit to Maryland.
In the latest reports, two Western officials and a Russian source told Reuters Moscow is sending advanced SA-22 anti-aircraft missiles to Syria. The system would be operated by Russian troops, rather than Syrians, the Western officials said.
U.S. officials in Washington also said they believed about 200 Russian naval infantry forces were now stationed at an airfield near the Syrian city of Latakia, an Assad stronghold, and that the number had increased in recent days.
PREPARING SYRIAN AIRFIELD
One official estimated that the majority of the forces were involved in preparing the airfield for future use.
Lebanese sources have told Reuters that at least some Russian troops are now engaged in combat operations in support of Assad`s forces. Moscow has declined to comment on those reports.
Obama said Russia would have to start using diplomacy rather than force to counter the influence of Islamic State militants. He said the group posed more of a threat to Russia than to the United States because of the country`s large Muslim population.
At a news conference in Moscow, Foreign Minister Sergei Lavrov said Russia was sending equipment to help Assad fight Islamic State. Russian servicemen were in Syria, he said, primarily to help service that equipment and teach Syrian soldiers how to use it.
Russian naval exercises in the eastern Mediterranean were long-planned and in accordance with international law, he said.
A source close to the Russian navy told Reuters a squadron of five Russian ships equipped with guided missiles had set off to conduct manoeuvres in Syrian waters.
"They will train to repulse an attack from the air and to defend the coast, which means firing artillery and testing short-range air defence systems, " the source said, adding that the exercise had been agreed with the Syrian government.
Russia has given notice of several rounds of navy drills with rocket firing tests in the sea off Syria from Sept. 8 to Oct. 7, according to Cypriot aviation authorities and international governmental databases of notices for airmen. Some flight paths will be temporarily closed.
Lavrov blamed Washington for cutting off direct military-to-military communication between Russia and NATO after the crisis in Ukraine last year. Such contacts were "important for the avoidance of undesired, unintended incidents", Lavrov said.
"We are always in favour of military people talking to each other in a professional way. They understand each other very well," Lavrov said. "If, as (U.S. Secretary of State) John Kerry has said many times, the United States wants those channels frozen, then be our guest."
U.S. officials say they do not know what Moscow`s intentions are in Syria. Momentum in Syria`s 4-year-old civil war has been shifting against Assad`s government, which has suffered battlefield setbacks this year at the hands of an array of insurgent groups.
Moscow, an ally of Damascus since the Cold War, maintains its only Mediterranean naval base at Tartous on the Syrian coast, and defending it would be a strategic aim.
In recent months NATO-member Turkey has also raised the prospect of outside powers playing a greater role in Syria, proposing a "safe zone" near its border, kept free of both Islamic State and government troops.
The war has killed 250,000 people and driven half of Syria`s 23 million people from their homes. Some have travelled to European countries, creating a refugee crisis there.
The dispatch of advanced anti-aircraft missiles like the SA-22, which the two Western officials said were on their way but had not yet arrived, would appear to undermine Moscow`s argument that its sole aim is to help Damascus fight Islamic State: the militants and other insurgents possess no aircraft.
"This system is the advanced version used by Russia and it`s meant to be operated by Russians in Syria," said one of the Western sources, a diplomat briefed on intelligence assessments.
A Russian source close to the navy said the delivery would not be the first time Moscow had sent the SA-22, known as Pantsir-S1 in Russian, to Syria. The system had been sent in 2013, the source said. "There are plans now to send a new set."
However, the Western diplomat said the new missiles would be more advanced than those deployed in the past.
French Foreign Minister Laurent Fabius said it was too early to judge what Russia`s motivations were in Syria, but ?"adding war to war" would not help resolve the conflict.
"If it`s about defending the base in Tartous why not? But ?if it`s to enter the conflict...." he said, without finishing the thought.
Diplomats in Moscow say the Kremlin is happy for the West to believe it is building up its military in Syria, calculating that this will give it more bargaining power in any peace talks.
Western and Arab countries have backed demands from the Syrian opposition that Assad must leave power under any negotiated settlement. Assad has refused to go, and all diplomatic efforts at a solution so far have collapsed.
Assad’s supporters have taken encouragement this week from an apparent shift in tone from some European states.
Britain, one of Assad’s staunchest Western opponents, said it could accept him staying in place for a transition period if it helped resolve the conflict.
France said on Monday he must leave power “at some point or another”. Smaller countries went further, with Austria saying Assad must be involved in the fight against Islamic State and Spain saying negotiations with him were needed to end the war.
The Syrian pro-government newspaper al-Watan saw Britain’s position as “a new sign of the changes in Western positions that started with Madrid and Austria”.
