CNN reported Dempsey was in his room at the time and "not in any danger" according to a spokesman.

Since arriving Monday, Dempsey has met with NATO and Afghan leaders to discuss changes in security on bases.

Twenty-three Americans have been killed in attacks by Afghan military and police personnel, out of a total 40.

The attacks prompted NATO commander Gen. John Allen on Friday to order troops at NATO headquarters and bases in Afghanistan to carry loaded weapons at all times.
