A car blast outside a Saudi mosque during Friday prayers killed four people, including its driver, in an attack that was "foiled" by the authorities, the interior ministry said.
The explosion went off as security officials approached the car as it was being driven to a parking lot near the Shiite mosque of Al-Unood in the Gulf city of Dammam, said a ministry spokesman quoted by the Saudi Press Agency.
"When they headed towards it, it exploded killing four people, at least one of them believed to be its driver," he said.
