CAIRO: Opponents of President Mohammed Morsi have set fire to offices of his Muslim Brotherhood in several Egyptian cities, clashing with his supporters after the Islamist leader assumed sweeping new powers.

State TV says Morsi’s opponents set fire to the offices in the Suez Canal cities of Suez, Port Said and Ismailia.

Clashes also erupted between the two sides in the Mediterranean city of Alexandria, the southern city of Assiut and in Giza, the sister city of the capital.

In Alexandria, Morsi opponents hurled stones at Brotherhood supporters outside a mosque and stormed a nearby office of the group.

The clashes came a day after Morsi announced sweeping new powers for himself, putting himself above judicial oversight.
