Three blasts, including a suicide bombing at the police headquarters, rocked the Egyptian capital on Friday, killing five persons and injuring nearly 100 on the eve of the anniversary of the 2011 uprising.
The first powerful blast was reportedly caused by a suicide attacker, who rammed his explosives-laden vehicle into a security fence around the Cairo Security Directorate, killing four and injuring 76 others, officials at the Interior and Health Ministry said.
In a second blast hours later, at least one person was killed when a small improvised explosive device went off after being thrown at a police vehicle near a metro station in Giza. At least 11 persons were reportedly wounded in the attack. Another improvised bomb hit a police station near the Giza pyramids. The blast did not cause any fatalities, an Interior Ministry official told State TV.
The deadly blasts have raised concerns that an Islamist insurgency is gathering pace in the polarised Arab nation as Egyptian forces have intensified crackdown on Islamists.
