Riyadh, Saudi Arabia ? The leader of al-Qaida in Saudi Arabia and two men who helped attack the world’s largest oil-processing complex were among five militants killed during police raids, authorities said Tuesday.

The announcement was the first acknowledgment by Saudi authorities that some attackers had escaped after Friday’s attack on the Abqaiq facility, which processes about two-thirds of the country’s oil for export.

Fahd Faraaj al-Juwair, the kingdom’s most-wanted terror suspect, and two militants who attacked the Abqaiq facility died in a Monday shootout, the Interior Ministry said in a statement carried by the official Saudi Press Agency. Two other militants also were killed.

Saudi authorities said al-Juwair and slain militants Ibrahim Abdullah Ibrahim al-Mutair and Abdullah Muhia Shlash al-Sulaiti al-Shamari were on the kingdom’s list of most-wanted terrorists issued in June.

Al-Juwair, who was in his mid-30s, was the leader of al-Qaida in Saudi Arabia and a longtime extremist.
