Helicopter crashes are not uncommon in Afghanistan and the Taliban and others often claim to have shot them down.

U.S. Defense Secretary Chuck Hagel left Afghanistan earlier on Monday. His visit was marred by a suicide bomb attack near where he was holding a meeting, and differences with Afghan President Hamid Karzai, who accused the United States of colluding with the Taliban.
