An American and British soldier died during a training exercise in Iraq, their respective officials said.

The announcements, from U.S. Army Central and the British Ministry of Defense, were sparse on details. The deaths occurred on Sunday during a training exercise at an air base in Erbil, located in the Kurdish region of northern Iraq. The United States and United Kingdom boosted their presence in the region to help combat ISIS, though they have also come under attack from Iran-allied Shiite fighters.
