CAIRO (AFP) - Two roadside bombs exploded near a patrol car in Cairo on Friday, and police fired tear gas at supporters of ousted president Mohamed Mursi in Alexandria, security officials in Egypt said.
One policeman was slightly wounded when his patrol car was hit by two roadside bombs in a Cairo suburb, the interior ministry said.
The capital has been rocked by several bombings and shootings targeting police over the past week.
On Jan 24, a day before the third anniversary of the 2011 uprising that toppled Hosni Mubarak, a car bombing hit police headquarters, one of four bombs targeting the force in the city.
Six policemen were killed that day.
Four days later, police general Mohamed Saeed, an aide to the interior minister, was killed outside his home by gunmen on a motorbike.
Supporters of Mursi, who was ousted by the army on July 3, had called for protests on Friday.
Police fired tear gas to disperse a pro-Morsi demonstration when the deposed Islamist's supporters clashed with opponents in the Mediterranean city of Alexandria, security officials said.
Similar pro-Mursi demonstrations were staged in Cairo, Sharqiya and Fayoum, they said.
The military-installed authorities have launched a deadly crackdown on Mursi's supporters, mostly Islamists, since his removal.
Rights group Amnesty International says that at least 1,400 people have been killed in the crackdown.
Mursi supporters continue to stage regular protests demanding his reinstatement.
