Aleppo, Syria's commercial hub and most populous city before the uprising against Assad erupted in 2011, has been witnessing heavy fighting since Assad's forces, backed by Shi'ite militia from Iraq and the Lebanese party Hezbollah, launched an offensive two weeks ago to retake rebel-held areas in the city.
