Syrian regime air strikes killed more than 30 people Saturday in the Latakia province, bastion of the ruling Assad clan, and the northern city of Raqa, a monitory group said.
Seven children were among at least 13 civilians killed in an air raid on Raqa, the only provincial capital in rebel hands, according to the Syrian Observatory for Human Rights.
It said the raid was apparently aimed at positions of the jihadist Islamic State of Iraq and the Levant (ISIS) which largely controls the city.
ISIS has been the dominant force in the city since its capture by rebels in March. Residents have held several protests against the policies of ISIS which follows an extremist line of Islam, according to the Observatory.
Latakia province is a stronghold of the Alawite minority of President Bashar al-Assad, apart from rebel-held pockets. Also in Aleppo province, further east, government troops stormed a village overnight, killing 12 people.
