ALEPPO -- Syria’s long and brutal civil war may be reaching a turning point.

Syria’s largest city, Aleppo, which was taken over in 2012 by anti-government rebels -- backed by the United States -- is slowly falling back into the control of the Assad regime.

Syria and its ally Russia, unleashed the full might of it’s air power on Kafranbel in Idlib killing dozens of civilians. The terror and is chaos captured here on amateur video just moments after the attack.



Air fire also rained down on Rastan in Homs where terrified children, some badly injured, were evacuated in panic.
