Air raids left 15 people killed in Syria's Aleppo Sunday, according to Agence France-Presse. Eight of the deceased were children.
"Fifteen people, including six men, an 18-year-old and eight children were killed in an aerial bombardment of the Ard al-Hamra neighbourhood [of Aleppo]," according to the Syrian Observatory for Human Rights.
The air raids allegedly attacked rebel-held areas of the city and caused extensive destruction.
In Adra, northeast of the country's capital, the Syrian Observatory told AFP that at least 28 people have been killed since Wednesday in fierce clashes between rebel and regime fighters.
"The number of civilian fatalities has risen to 28... among them Alawites, Shiites and Druze," said the Observatory based on its activist sources on the ground.
