CAIRO, Egypt - Egypt's interior minister says his convoy was targeted by a "large" explosive device that was likely detonated by remote control.

Speaking on state television after Thursday's attack in an eastern Cairo district, a clearly shaken but unscathed Mohammed Ibrahim said the explosion targeted his own car. He says four other cars in the convoy were damaged.

Ibrahim said two police officers in the convoy were in serious condition and that a child who was near the explosion suffered a serious leg injury.

Egypt has been hit by political unrest and violence since the July 3 ouster of Islamist President Mohammed Morsi. The attack on Ibrahim, who is in charge of the country's police, marked the first time a senior government official has been targeted.
