RIYADH — Security authorities are conducting an investigation into a drive-by shooting in the capital late Sunday in which two Saudi police officers were injured, a police spokesman said in a statement carried by the Saudi Press Agency on Monday. “A security patrol was carrying out its duties in Riyadh when it came under fire from an unknown vehicle” in an attack that “left two policemen wounded,” said the spokesman. The two were admitted to hospital and “their health situation is stable,” the statement said. Saudi authorities said on Thursday the security forces were on a heightened state of alert because of the Saudi-led campaign against Houthi rebels in Yemen. In January, three border guards, including a commander, were killed in a desert area north of Arar, during a fight with infiltrators.
