Iraqi border guards have captured a Saudi who admitted he was involved in last month's suicide attack on the Abqaiq oil facility in eastern Saudi Arabia, an Iraqi military spokesman said Wednesday. Abdullah Salah al-Harbi was apprehended 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. The spokesman quoted al-Harbi as saying that five other Saudis crossed the border with him but went missing in the Iraqi desert. Iraqi forces are searching for them, al-Jabiri 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."
