Five killed as gunmen mow down oil workers

Two Britons were feared dead today after gunmen opened fire indiscriminately on staff at an oil refinery in Saudi Arabia, a company official said.

The pair were among five workers killed by the attackers who burst into offices at the complex co-owned by Exxon Mobil and the Saudi company SABIC in the port city of Yanbu on the Red Sea coast, north of Jeddah.
