One person has been killed and scores more have been wounded in a blast targeting police vehicles near a metro station in Cairo, Egyptian security officials said.

A second explosion near tourist sites – possibly carried out by two suicide bombers – went off today less than two hours after a downtown blast that police said was either a suicide bomber or an assailant throwing an explosive device off a bridge.

There has been a second explosion in Cairo, according to local police.

An explosion was heard in central Cairo today, and the remains of a body, covered with newspapers, were seen lying beneath a bridge.
