There is anger in western Aleppo where Syrians are blaming the US military for the deaths of civilians.
Opposition activists say the US was responsible for hitting a residential building not far from a known headquarters of Syria's al-Qaeda branch, the Nusra front.
They say 11 people, including four children, were killed - a claim Al Jazeera cannot verify.
