In an amateur video posted online, a man held up to the camera a severed foot from the air raids, while crowds scrambled among rubble, hoarsely shouting “God is Great!” as they came across corpses.
Flames and dust from the smashed building and cars darkened the sky.
One man rhythmically smashed a hammer against a jammed door of a vehicle containing charred bodies.
The videos appeared genuine and corresponded with other Associated Press reporting of the events depicted.
In the town of Marea north of Aleppo, a barrel bomb that exploded near a school used by Syrian fleeing fighting in other areas killed three members of the same family, according to Abu Faisal and the Observatory.
Schools decided to close Monday in opposition-held parts of Aleppo to avoid more casualties, citing Sunday's attacks in Marea, the Aleppo Media Center reported.
Syrian officials have not commented on the air raids in Aleppo, the country's largest city, and a major front in the war since the rebels launched an offensive there in mid-2012.
