In a rare ground attack deep into Syria, U.S. Army commandos killed a man described as the Islamic State’s head of oil operations, captured his wife and rescued a woman whom American officials said was enslaved.

A team of Delta Force commandos slipped across the border from Iraq under cover of darkness Saturday aboard Black Hawk helicopters and V-22 Osprey aircraft, according to a U.S. defense official knowledgeable about details of the raid. The official was not authorized to discuss the operation publicly and spoke on condition of anonymity.
