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 on Tuesday 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.
"Prime Minister Beblawi has declared the Muslim Brotherhood as a terrorist organisation," MENA quoted the premier's spokesman Sherif Showky as saying.
Egypt's military-installed authorities have often accused the Muslim Brotherhood of funding and training militants who regularly launch attacks on security forces in the restive Sinai Peninsula.
