On Friday, six children were killed in Maarrat al-Nu’man when the regime forces hit the northern town with cluster bombs, the Idleb Media Center reported.
An array of towns in Idleb province came under regime artillery fire in latest regime escalation against the buffer zone area.
The artillery fire targeted the towns of Maarrat al-Nu’man, Sarmin, Saraqeb and al-Khawin.
During the week, 19 civilians were killed following two separate regime airstrikes on Khan Sheikhoun.
Idleb has been hit by sporadic regime shelling for weeks, despite the buffer zone deal between Russia and Turkey.
Turkey, which backs moderate Syrian rebels, and Russia, the regime’s principal foreign ally, agreed in September to create a demilitarised zone in the northwestern Idleb region that would be evacuated of all heavy weapons and hardline fighters.
Since the Syrian revolution erupted in 2011, more than 560,000 people have been killed, and more than six million people have been displaced.
