In the Syrian city of Aleppo, nearly 300,000 people are trapped without access to food, fuel or basic medical supplies. Government forces, aided by Russian air power and Iranian-backed militias, have cut off the eastern area of the city held by rebel troops. President Bashar al-Assad believes that whoever controls Aleppo will win the civil war and has stepped up the bombardment there. There are unverified reports his regime has even used napalm in Darayya, west of Damascus. Meanwhile, rebels have launched an offensive to lift the siege. Here, writing under a pseudonym, Syria-born charity worker, Ahmed Khalid, working with Save The Children alongside aid workers in Aleppo delivers a shocking dispatch on the broken city.
