Rebel and regime bombardment in Syria's Aleppo on Sunday killed at least 14 civilians, emergency workers and a monitor said, on the third day of renewed violence in the battered city, AFP reports.

Rebel rocket fire on government-held parts of the northern city killed six civilians, including a woman and two children, said the Syrian Observatory for Human Rights.

And a barrage of government air strikes that began around midday on Sunday left at least eight civilians dead.

The strikes killed five people in a fruit and vegetable market in the neighborhood of Sakhur, said a member of Aleppo's civil defense.

Regime aerial bombardment left two civilians dead in the district of Shaar and another in Bab al-Nayrab, the source added.
