Aleppo, Syria

A bomb maker for Syrian rebel forces works in a makeshift bomb factory in the country’s largest city, Aleppo. As the civil war in Syria dragged on into its second year, conflict broke out between factions within the armed opposition forces. Much of the in-fighting was directed against the al-Qaeda-linked Islamic State of Iraq and the Levant, and other Islamist groups focused on enforcing sharia law. As rebel factions turned on one another, government troops took the opportunity to launch concerted attacks on rebel-held and contested areas, subjecting Aleppo to heavy bombardment.
