Fourteen people have been injured in clashes in eastern Saudi Arabia, state media say. They said the unrest in the province of Qatif late on Monday had been incited by "a foreign country", without elaborating. Saudi Arabia's minority Shia population is concentrated in the east, the scene of protests earlier this year. State media said eight of those wounded were security personnel and three were civilians. State news agency SPA quoted the interior ministry as saying that "a group of outlaws and rioters on motorbikes" had gathered in al-Awamia village near the city of Qatif, "carrying petrol bombs". The group was responsible for acts leading to "insecurity with incitement from a foreign country that aims to undermine the nation's security and stability", SPA reported. Saudi mentions of foreign meddling are normally veiled references to Iran, the region's main Shia power, observers say.
