American-led intervention in Iraq (2014–2021)
United States Defense Secretary Ashton Carter says the U.S. will begin "direct action on the ground" against the ISIL forces in Iraq and Syria, aiming to intensify pressure on the militants as progress against the militants remains elusive. The U.S. has done some special operations raids in Syria, e.g., last week's rescue operation with Kurdish forces in northern Iraq to free hostages held by ISIL. Carter also said the U.S. would intensify the air campaign against ISIL with heavier airstrikes and will focus on Raqqa, the group's declared capital in Syria.
