Purported Gaddafi gunmen ‘shoot protesters’

New footage has emerged from the first moments of the uprising in Libya, showing gunmen – alleged to be part of groups loyal to longterm leader Muammar Gaddafi – apparently shooting unarmed protesters dead.

As armed men dragged people from Benghazi’s mosque, others were left to die where they fell.

Al Jazeera’s Sue Turton reports from the city on the violence on the streets during the first three days of protests.
