WASHINGTON (AP) " A U.S. military raid that killed an Islamic State leader in Syria last spring yielded intelligence that allowed the U.S. to more effectively target the extremist group's oil revenues, the State Department's top diplomat for energy affairs said Tuesday.
Amos Hochstein, a special envoy and coordinator for international energy affairs, told reporters at the Pentagon that the raid by U.S. special operations forces in May was a key to building a military and diplomatic plan to hit the extremists' most important source of income.
The raid killed Abu Sayyaf, who was known as the Islamic State's oil emir. Sayyaf's wife, an Iraqi known as Umm Sayyaf, was captured. U.S. officials have said she was cooperative during interrogations and provided significant amounts of useful intelligence. She is now in Iraqi custody.
"With that raid we got this enormous amount of information that was very detailed as to how they operated their energy sector and allowed us to learn more about the operation and how to attack it or address it," Hochstein said. It enabled the U.S. to "put together the picture" of the most effective way to attack the group's oil infrastructure in Syria, he said.
"We were able to, starting this past summer, look more strategically at which assets in Syria are a better-value target," he said.
