Egypt violence: Clashes erupt in Alexandria

Fresh clashes have broken out in Alexandria as supporters and opponents of Egypt's president stage final rallies ahead of a referendum on a draft constitution, due to start on Saturday.

Opponents say the draft document has been crafted poorly and without proper consultation, and is too Islamist.

President Mohammed Morsi insists the constitution is needed to complete the transition from Hosni Mubarak's rule.

Egyptians are split into two rival camps on a draft constitution referendum, which plunged the country into turmoil and violence.
