Anti-Gaddafi graffiti on the walls of Libya

During the four decades that Col Muammar Gaddafi ruled Libya, his official portraits were everywhere. Now that he has been overthrown, artists are revelling in their new-found freedom and turning this tradition on its head. Caricatures of the vilified leader have been painted on walls throughout the country.

Benghazi, the epicentre of the uprising that swept Libya, has become the hub for this new form of street art. Among the city's artists is 22-year-old Ibrahim Humaid, an engineering student, who started painting caricatures of Col Gaddafi while he was manning a checkpoint during the revolution.
