The US Embassy in Saudi Arabia said Westerners face possible attack from unidentified extremists in the central province of al-Qassim, in the first warning of its kind this year. "We have received credible information that an unidentified extremist (s) in Saudi Arabia may be planning to attack Westerners working and living in al-Qassim, Saudi Arabia," the embassy said in a statement posted on its website.
"The timing and method of potential attacks are currently unknown," said the statement dated August 4, urging US citizens to "exercise prudence and enhanced security awareness at all times". Qassim is among the most conservative regions in the kingdom. The key US ally is ruled by the Al Saud family in alliance with clerics from the austere Wahhabi school of Islam.
A Saudi foreign ministry spokesman declined to comment on the alleged threat by saying the statement "concerns only the US embassy". "The kingdom continues its effort to confront terrorism and terrorist operations. Thanks to God, the kingdom has achieved and still achieves great successes in this endeavour," Osama al-Noghali told Reuters.
Militants carried out attacks against Western targets, government symbols and oil facilities between 2003 and 2006. The attacks included suicide bombs at Western housing compounds, the interior ministry's headquarters in Riyadh and oil and petrochemical companies, plus an attempt to storm the world's biggest oil processing plant at Abqaiq in 2006.
