Among the areas that have managed to stay relatively free from violence is the town of Takad in western Aleppo countryside, where Dr Mustafa Ajaj, his wife and their three children have lived for over three years. Dr Ajaj, who manages a primary healthcare centre in Takad, says the population of the town and the nearby hills has spiked in recent weeks, from around 20,000 to 30,000.
But as the bombing draws closer, people have started to flee Takad too and 42-year-old Dr Ajaj fears he and his family might be next.
