A massive car bomb rocked northern Cairo and wounded six policemen at a state security building on Thursday, officials said. Egypt's interior ministry said in a statement a man "suddenly stopped his car in front of the state security building, jumped out of it and fled on a motorbike that followed the car." No deaths were reported. The explosion partially destroyed the building and left a crater in the street in Shubra Al-Khaima, a northern neighbourhood in the Egyptian capital. No one has claimed the attack but militants affiliated with ISIS in northern Sinai have been responsible for recent bombings in Cairo.
