Two Saudi policemen were slightly wounded yesterday as they came under fire from gunmen in a car north of the capital, the Interior Ministry said. A highway patrol came under fire as it chased a speeding car on the Riyadh-Qassim Expressway, Maj. Gen. Mansour Al-Turki, the ministry's spokesman said. "The windshield was smashed and the two policemen who were in the car were injured," he told the Saudi Press Agency. The gunmen escaped, and security forces are combing the area in search of them, he added.
