While planes, tanks, and drones attack the so-called Islamic State in Iraq and in Syria, two young men from Tunisia are taking the fight to them in a very different way - with rap music.

They risk their lives to deter those who would follow the thousands who've already gone to Iraq, Syria and Libya to fight for IS.

Hugh Sykes meets DJ Costa, whose brother Yussuf was recruited by IS and killed in Syria, and Dya Hammadi who fled his home town after being kidnapped for his anti-Islamist raps.

"Those imams who tell you jihad. Think about it, ask some questions. Why are they coming after you to offer you jannat (paradise)?" - Brainwashing by DJ Costa.
