Syrian regime shelling killed 10 civilians in the Idlib region, which is under the control of Tahrir al-Sham, on Thursday (April 18th), AFP reported.
Rocket fire targeted a village and an adjacent camp for the internally displaced in Idlib's southeastern countryside, according to the Britain-based Syrian Observatory for Human Rights.
Four women and three children were among the 10 civilians killed, the monitor said.
Another 30 people were wounded, it said.
Russia and Turkey in September inked a buffer zone deal to prevent a massive regime offensive on the Idlib region, near the Turkish border.
But the region of some three million people has come under increasing bombardment since Tahrir al-Sham took full control of it in January.
The UN has expressed concern over escalating violence, warning that the flare-up is threatening aid deliveries to some 2.7 million people in need.
