Egypt's official news agency says 149 people have been killed in clashes across the nation between supporters of the ousted Islamist president and security forces.

The agency quoted a Health Ministry spokesman who also said 1,403 people have been wounded.

The casualty figure followed simultaneous raids by police early on Wednesday on two sprawling encampments of Morsi supporters. The raids sparked running street battles elsewhere in Cairo and other Egyptian cities.

Interim President Adly Mansour declared a monthlong state of emergency, ordering the armed forces to support the police in efforts to restore law and order and protect state facilities.

Morsi was ousted in a July 3 military coup that followed days of mass protests by millions of Egyptians demanding that he steps down.
