A car bomb exploded near a state security building in northern Cairo early Thursday, injuring 29 people, Egypt’s Health Ministry said.
The driver of the car parked it in front of the National Security Building in the northern suburb of Shubra al-Kheema and then was picked up by a motorcycle and fled, the ministry said.
Among the 29 wounded were six police officers, the Interior Ministry said.
No group immediately claimed responsibility for the attack.
In recent months, militants have increasingly launched brazen and deadly attacks. The frequency of the attacks picked up after Egypt’s army overthrew President Mohamed Morsy — a former Muslim Brotherhood leader — following a popular uprising in July 2013.
Earlier this week, President Abdel Fattah el-Sisi signed a tough counter terrorism law that gives Egyptian authorities sweeping surveillance and detention powers.
