埃及一座安保大楼遭炸弹袭击 14人死亡
A huge explosion at a security building in northern Egypt has killed at least 14 people and injured more than 100, officials and state media say.
埃及官方媒体称，北部地区一座安保大楼发生大型爆炸案，造成至少14人死亡、100人受伤。
The impact of the blast was felt 12 miles away
The blast, reportedly caused by a car bomb, led to the partial collapse of the building in the city of Mansoura.
Interim Prime Minister Hazem Beblawi called it "an act of terrorism".
Attacks on Egypt's security forces and police have increased since the army removed Islamist President Mohammed Morsi in July.
No group has so far claimed responsibility for Tuesday's blast.
Mr Beblawi told satellite channel ONTV: "The state will do its utmost to pursue the criminals who executed, planned and supported that attack."
The Muslim Brotherhood - which supports Mr Morsi and has been banned by the interim authorities - condemned the bombing.
"Muslim Brotherhood considers this act as a direct attack on the unity of the Egyptian people," it said in a statement.
