Six Egyptian policemen were wounded in a bomb attack on a bridge in the capital on Friday, officials said.
The attack shattered a tense calm in Cairo after a spate of bombings on January 24 killed six policemen, in an escalation of a militant campaign following the overthrow of Islamist president Mohamed Morsi.

The interior ministry said two small bombs exploded near policemen stationed on a bridge near central Cairo. At least six were wounded in the attack, the health ministry said.
