According to World Magazine:
A U.S. special operations team conducting a pre-dawn raid in Syria on Friday killed senior Islamic State (ISIS) leader Abd al-Rahman Mustafa al-Qaduli. The terrorist, also known as Abu Ala al-Afri, was considered the group’s second-in-command. U.S. Defense Secretary Ash Carter confirmed the raid during a news conference this morning, but declined to give details. He said the operation was part of ongoing efforts to cut down the terror group’s leadership team. Another U.S. official said the raid was prompted by the ISIS attack in Belgium on Tuesday. Carter described Al-Afri as the ISIS finance minister, but he also had a hand in external affairs and plots. Before joining al-Qaeda in 2004, al-Afri was a physics professor. He spent time in an Iraqi jail and joined ISIS after his release in 2012.
