Egyptians officials say a car bomb exploded Thursday near the convoy of the country's interior minister in Cairo, wounding four people.
Security officials say the explosion took place near home of Interior Minister Mohamed Ibrahim, who was not hurt in the blast.
State media described the attack as a failed assassination attempt. There is no word on who is responsible or how the explosion was detonated.
The attack occurred in the Nasr City neighborhood of northeast Cairo, where security forces last month stormed an Islamist sit-in, killing hundreds of supporters of ousted President Mohamed Morsi.
