Air strikes by Syrian government forces killed at least 21 people, including six children, and wounded 50 today in the northern provinces of Aleppo and Idlib, a monitor said.
In the south of Aleppo city, a small girl was among four civilians killed in the rebel-held neighbourhood of Ferdus, said the Syrian Observatory for Human Rights.
Another seven civilians died in Deir Hafer and Bab, two areas located in the east and north of Aleppo under the control of the Islamic State jihadist group, said the Britain-based group.
Explosives-filled barrels and missiles were used in the wave of bombing, which left 50 people wounded.
In Idlib, air strikes killed 10 people, five of them children, said the Observatory, which relies on a network of sources on the ground for its reports.
A newly formed rebel alliance calling itself the Army of Conquest has seized key positions in Idlib province in recent weeks, including the provincial capital of the same name, the town of Jisr al-Shughur and a military headquarters.
