BEIRUT – The Syrian military has recently started using new types of air and ground weapons supplied by Russia, a Syrian military source told Reuters on Thursday, underlining growing Russian support to Damascus that is alarming the United States.
“The weapons are highly effective and very accurate, and hit targets precisely,” the source said in response to a question about Russian support. “We can say they are all types of weapons — be it air or ground.”
The source said the army had been trained in the use of the weapons in recent months and was now deploying them, declining to give further details other than saying they were “new types.
The Russian government said on Thursday its military support for Damascus was aimed at fighting terrorism, safeguarding Syria’s statehood and preventing a “total catastrophe” in the region.
It includes a larger Russian military presence on the ground in Syria, where President Bashar Assad has faced increased pressure this year from rebels fighting to topple him, but its full scope and intentions remain unclear.
Washington, which wants Assad gone from power, has said it believes Russia is undertaking a significant military buildup that could exacerbate the war.
The United States, along with Saudi Arabia and Turkey, have supported insurgents battling to unseat Assad, whose foreign military backing has so far come mostly from Iran and its Lebanese ally Hezbollah.
A U.S.-led coalition is also bombing Islamic State militants in Syria and Iraq, raising the prospect of a potential clash between U.S. and Russian air forces.
In a possible sign of newly assertive posture by Assad, the Syrian air force launched heavy airstrikes on the Islamic State-held city of Raqqa, an important base of operations for Islamic State in Syria often targeted by the U.S.-led coalition.
The airstrikes, reported by activists in Raqqa, were not confirmed by the Syrian military.
The U.K. based Syrian Observatory for Human Rights said at least 18 were killed in the raids that hit several areas in the city and it’s outskirts, including a maternity hospital.
The government, which by Assad’s own admission faces a military manpower problem, is seeking to shore up control over the cities of the west after losing much of the rest of Syria to an array of insurgents, including Islamic State.
The Obama administration said Wednesday it was considering how to respond to a Russian proposal for military talks over Syria, which may be about “deconfliction” — ensuring that U.S. and Russian aircraft do not come into conflict in Syria.
On Thursday, White House spokesman Josh Earnest said: “The United States remains open to tactical, practical discussions” with Russia over the fight against Islamic State in Syria.
Russia says Assad should be part of international efforts to fight Islamic State. The United States believes he is part of the problem and rejects that idea.
The war has already killed 250,000 people. Four million people have fled Syria and almost twice as many are displaced inside it. Tens of thousands of Syrian refugees have been arriving in Europe, part of the biggest migration crisis to hit that continent in decades.
Activists said Syrian government warplanes had mounted at least 12 airstrikes in Raqqa, often described as Islamic State’s de facto capital. The raids started at around 11:30 a.m. and came in three separate waves that hit eight targets.
The strikes hit close to at least four Islamic State offices, including one used by its self-appointed religious police force, said an activist in Raqqa who was contacted via the internet and declined to be named for security reasons.
Islamic State imposed a curfew in two parts of the city.
An activist group called Raqqa is Being Slaughtered Silently said on its Twitter feed: “There is news about a large number of martyrs and wounded.”
The Syrian Observatory for Human Rights, which reports on the war using a network of sources on the ground, said government forces had recently started using new weapons including guided air-to-surface missiles.
“There are modern weapons that the regime didn’t previously have, be they rocket launchers or air to ground to missiles,” said Rami Abdulrahman, director of the Observatory.
The prime minister of Israel, which has mounted its own airstrikes in Syria against both Syrian military and Hezbollah targets, is due in Russia next week for talks with President Vladimir Putin on the expanding Russian military presence.
Reuters has previously reported on U.S. assessments that Russia has sent about 200 naval infantry forces, battle tanks, artillery and other equipment to an airfield near Latakia.
U.S. officials said on Wednesday the United States had identified a small number of Russian helicopters at a Syrian airfield.
Russia has been sending about two military cargo flights a day to an air base at Latakia on the government-controlled Syrian coast, U.S. officials say.
Lebanese sources familiar with military and political developments in Syria have also previously told Reuters that Russians are taking part in military operations in the country. Syrian officials say the Russian military presence is restricted to experts.
Hezbollah has deployed directly in combat, while Iran has mobilized militias and sent military advisers.
