A convoy of vehicles loaded with relief material and fuel has been destroyed by Russian airstrikes in the town of Atarib, located nearly 25 km to the west of Aleppo.
According to local activists and eyewitnesses, Russian fighter jets pounded the trucks with air-to-surface missiles while en route to the frontlines in southern Aleppo.
Six people have been confirmed dead, dozens others wounded in the attack.
Jihadi rebels are launching a full-scale offensive against government troops in southern Aleppo in bid to lift the siege on insurgent-controlled districts in the eastern Aleppo.
Weeks ago, the Syrian Army cut off the Castello Road; the main and only supply route to rebel-held parts of the northern city, leaving thousands of fighters, as well hundreds of thousands of civilians trapped and entirely encircled.
Syrian and Russian governments embarked on a humanitarian operation, offering safety corridors for civilians as well as fighters willing to lay down arms.
