CAIRO (TheBlaze/AP) — Egyptian security officials say a large bomb has exploded near a national security building in the Shubra neighborhood of Cairo.
There were no immediate reports of injuries or deaths, but security officials told Reuters that casualties were feared. For blocks around the blast site, glass from blown-out windows could be seen on the street.
Security officials initially said they believed the blast to have come from a car bomb.
According to a statement from Egypt's interior ministry, six police officers were wounded in the blast and taken to the hospital. The assailant fled the scene on a motorcycle.
The bombing comes amid a wave of attacks and killings this summer, including the assassination of Egypt's attorney general by a car bomb in Cairo.
