3rd explosion rocks Casablanca neighborhood

A third explosion rocked a Casablanca neighborhood where two bombers blew themselves up earlier Tuesday. The blast in the middle of a boulevard in the working-class Hay Farah neighborhood came as police were combing buildings and rooftops for possible accomplices of the bombers behind the earlier blasts. Ambulance sirens wailed after the third explosion ripped through the neighborhood, though it was not immediately clear whether there were any deaths or injuries. The explosions, weeks after the bombing of a Casablanca Internet cafe, promised to further rattle the North African kingdom whose first high-profile brush with Islamic terrorism came in five suicide bombings in the city in May 2003.
