Aleppo is Syria's largest metropolitan area and a millennia-old commercial capital. Today, however, it is a relative ghost town, threatened by regime bombing from the air and a militant offensive on the ground.

From secret tunnels beneath the ancient city to threatened frontline outposts in Aleppo's ruined medieval center, VICE News followed the Islamic Front as they battled to retain control of the capital of the Syrian revolution against overwhelming odds.
