Babiris Meshaal, a civil defense official based in Aleppo, told Anadolu Agency that a total of 30 civilians had been killed and many others injured in the airstrike.
He added that the warplanes belonged to Russia or Syrian regime.
Since Sept. 19, when the Bashar al-Assad regime announced the end of a weeklong truce sponsored by Washington and Moscow, Syrian and Russian warplanes have pounded opposition-held parts of Aleppo.
Scores of civilians have reportedly been killed or injured in the attacks, which remain ongoing.
Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on pro-democracy protests -- which erupted as part of the "Arab Spring" uprisings -- with unexpected ferocity.
The Syrian Center for Policy Research, a Beirut-based NGO, has put the total death toll from the five-year conflict at more than 470,000.
