US special forces have killed a senior Islamic State (IS) member and captured his wife in a rare raid in eastern Syria, the Pentagon says.
Abu Sayyaf helped direct oil, gas and financial operations for IS, as well as holding a military role, the US Department of Defense statement said.
He was killed when he engaged US forces, the statement said.
The operation in al-Amr was authorised by President Barack Obama and was carried out by forces based in Iraq.
None of the US troops involved in the overnight operation were killed or injured, the White House said.
