The trial of the so-called "camel battle", one of the bloodiest attacks on protesters during the Egyptian uprising, has begun in Cairo.
On February 2, horse and camel riders stormed into Tahrir Square, attacking protesters with whips and swords. Clashes between opponents of former President Hosni Mubarak and his loyalists ensued.
Seven months later, the people accused of being behind the attack stand trial.
