The U.S. military says an F15 fighter jet crashed in eastern Afghanistan early Saturday, killing the two crew members on board.
A military statement says the plane went down during an operation in the region.
The military did not indicate why the plane went down, but the statement said the crash was not caused by "hostile fire."
Coalition forces are engaged in a major offensive in southern Afghanistan to drive Taliban militants out of their strongholds, and to maintain security ahead of a presidential election in August.
On Friday, a roadside bomb killed 11 civilians, including five children, as they were traveling to a shrine in southern Afghanistan's Kandahar province.
The attack happened in Spin Boldak district, a major cross border route between Afghanistan and Pakistan.
