MANAMA, Bahrain – A day after the first attack on Saudi Arabia’s vital oil infrastructure, the Saudi branch of al-Qaida warned in an Internet statement Saturday that suicide bombers will target more oil facilities. “There are more like them who are racing toward martyrdom and eager to fight the enemies of God,” the posting said. “You will see things that will make you happy, God willing.” A strike on the Abqaiq complex, near Saudi Arabia’s eastern Persian Gulf coast, could have been devastating. Nearly two-thirds of the country’s oil flows through the facility for processing before export. The attack, which was claimed by al-Qaida and repelled by Saudi security services, demonstrated Saudi Arabia’s success in putting tough security around the oil industry, the source of the royal family’s wealth, oil analysts said.

One bomber collided with the closed gate, exploding and blowing a hole in the fence, a senior Saudi security official said. The second bomber drove through the hole before police opened fire, detonating his car, the official added on condition of anonymity because of the sensitivity of the issue. Witnesses on Friday reported that security forces traded fire with gunmen outside the facility after the explosions and that a hunt for attackers continued for hours. Saudi officials have not reported the capture of any assailants. At least two attackers and two security guards were killed, the state news agency reported. Eight foreign workers at the facility – all from South Asia – were wounded, a former Aramco employee told The Associated Press on condition of anonymity. In another Web statement, al-Qaida said it carried out the attack “based on the instructions of our leader, Osama bin Laden” and identified the two slain suicide bombers as Abdullah Abdul-Aziz al-Tweijri and Mohammed Saleh al-Gheith. It denied that the bombing was foiled and gave its own account of the attack. It claimed that al-Qaida fighters overcame guards at the gate, killing three and forcing others to flee. The fighters then opened the gate for a car that entered and blew up, it said, without specifying what the blast targeted. The authenticity of the statements could not be independently confirmed. Crude oil prices jumped by more than $2 a barrel on world markets after the attack. But Saudi Oil Minister Ali Naimi swiftly issued assurances that the violence did not affect oil operations. On Saturday, he stressed to U.S. Commerce Secretary Carlos Gutierrez at a meeting in Riyadh that the kingdom would “ensure the flow of oil despite the terrorist threats.” Al-Qaida militants launched a campaign of violence in Saudi Arabia – bin Laden’s birthplace – in 2003. Attacks on oil infrastructure could represent a new tactic. Previous targets were peripherally related to the oil industry – expatriate oil workers living and working in the kingdom. Bin Laden first called for attacks on oil facilities in December 2004. Analysts and diplomats said Friday’s events were proof that increased security at oil installations has paid off for the Saudi kingdom. “It’s a success story,” said Fareed Mohamedi, head of country analysis at Washington-based PFC Energy. “It’s a bit too close for comfort, but it certainly shows that they can repel these types of attacks.” Mohamedi said the Saudi government typically places remote sensors in the desert surrounding oil complexes and several fences around the facilities themselves. About 25,000 security personnel man checkpoints on roads leading to the facilities and gates into the compounds. Saudi security forces have largely had al-Qaida’s branch in the kingdom on the run over the past year, arresting hundreds of suspects. They killed or captured all but one of the top 26 militants on a most-wanted list issued in December 2003, then did the same with 10 of the 15 on a second list issued in June. Friday’s attack was the first major strike since December 2004, when five gunmen attacked the U.S. Consulate in the Saudi port city of Jiddah. Five consulate employees from the Middle East and Asia and four attackers were killed. Ten people were wounded. Analysts said it was too early to say whether the Abqaiq bombing signaled a new, aggressive campaign. But the choice of oil facilities should increase concerns, they said. “If the Saudi system goes down, then you will have a real problem, and for oil prices, the sky is the limit,” Mohamedi said. “You’re attacking the absolute heart of the world oil system.” Saudi Arabia holds over 260 billion barrels of proven oil reserves, a quarter of the world’s total. It currently puts out about 9.5 million barrels per day, or 11 percent of global consumption. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
