At least four people have been killed when a car exploded in the parking lot of a Shi’ite mosque in Dammam in Saudi Arabia during Friday prayers, but authorities said the militants failed in their bid to hit the mosque itself.<br /><br /> Security forces apparently became suspicious of the vehicle parked near the mosque which exploded as they walked towards it. <br /><br /> The attack comes one week after a deadly suicide bombing in Qatif that killed 21 people, including two children.
