Rebels battling the Syrian army and its allies near Aleppo said on Monday they had received new supplies of U.S.-made anti-tank missiles from states opposed to President Bashar al-Assad since the start of a major government offensive last week.
The rebels from three groups contacted by Reuters said new supplies had arrived in response to the attack by the army, which is backed up by Russian air strikes and on the ground by Iranian fighters and Lebanon's Hezbollah.
The delivery of the U.S.-made TOW missiles to rebels in Aleppo and elsewhere in Syria appears to be an initial response to the new Russian-Iranian intervention. Foreign states supporting the rebels include Saudi Arabia, Turkey and Qatar.
But officials from one of the Aleppo-based rebel groups said the supplies were inadequate for the scale of the assault, one of several ground offensives underway with Russian air support.
"A few (TOW missiles) will not do the trick. They need dozens," said one official, declining to be named due to the political sensitivity of the military support program.
A number of rebel groups vetted by states opposed to Assad have been supplied with weapons via Turkey, part of a program supported by the United States and which has in some cases included military training by the Central Intelligence Agency.
These groups fight under the banner of the "Free Syrian Army" - a loose affiliation of rebels that do not operate with a centralized command structure and have been widely eclipsed by jihadist groups such as the Nusra Front and Islamic State.
