Violent clashes have broken out in cities across Egypt

Violent clashes have broken out in cities across Egypt in a day of protest after President Mohamed Morsi granted himself sweeping new powers.

In Alexandria, Egypt's second largest city, protesters stormed the headquarters of Mr Morsi's Muslim Brotherhood party throwing chairs and books into the street and setting them on fire.

Police fired tear gas on crowds gathered in Tahrir Square, in Cairo, the scene of the violent clashes during the overthrow of the former president, Hosni Mubarak.
