At least 22 civilians – among them 10 children - have been killed in Syria"s northwest region as Russian-backed government forces continued air raids and shelling in the last rebel-held territory in the war-torn country, according to volunteer medics.

At least 16 people were killed and scores wounded when a ground-to-ground missile struck a camp for displaced people in the village of Qah on Wednesday, said Ahmed Yarji, a spokesman for Syrian Civil Defence, also known as the White Helmets.

Among those who lost their lives were 10 children and three women, Yarji told Al Jazeera.
