Iraqi border guards captured a Saudi who admitted he was involved in the suicide attack on the Abqaiq oil facility in Saudi Arabia, an Iraqi military spokesman said Thursday. Abdullah Salah al-Harbi was detained Tuesday by Iraq border guards in the desert along the border between the two countries, said Saadoun al-Jabiri, a spokesman for the Iraqi border guard force. He quoted al-Harbi as saying five other Saudis crossed the border with him but disappeared in the Iraqi desert. Iraqi forces were searching for them, the border guard spokesman said. Al-Jabiri quoted the Saudi as telling interrogators that "the last operation I took part in was last week's attack on oil facility in Abqaiq." Al-Harbi also said he was wanted by Saudi authorities who had carried out raids around his home, al-Jabiri said. Al-Harbi told interrogators he was headed to the predominantly Sunni northern Iraqi city of Mosul, where he planned to meet cattle merchants who have links with al-Qaida, al-Jabiri said. "I came to Iraq to fight Americans, not Iraqis," the spokesman quoted al-Harbi as saying.
