Egyptian Prime Minister Hazem Beblawi has declared the country’s Muslim Brotherhood movement a “terrorist” organisation, state news agency MENA reported, quoting the premier’s spokesman.

Beblawi’s remarks came just hours after a car bomb ripped through a police headquarters in the city of Mansoura, north of Cairo, killing at least 14 people, mostly policemen.

Scores more have been wounded in the attack, medics and officials said.
