"Life in the small, northwest Syrian town of Salma has become hell, says one paediatrician who decided to stick around. Where 10,000 people once lived tucked into the hills of the Idlib governorate, now only a few remain.

Civilians and rebels mix in the town's shattered streets, where life goes on as best it can. Sue Turton reports from Salma."
