The civil war in Syria has seen a fierce battle between President Bashar al-Assad’s regime and the rebels. The rebels who lack the resources of Assad's government forces, have had to improvise and build their own bombs, missiles and mortar shells.
The fighters have been fighting in the besieged city of Aleppo using these homemade weapons. One weapon of choice is nicknamed the 'hell cannon'. The resistance fighters take great pride in the arm that usually fires out propane gas cylinders.

The "Borkan" is made out of four tubes attached to a loader, which can fire four shells at a time, and have a range of three kilometres (1.86 miles). Photograph: Abdalrhman Ismail/Reuters
