A U.S. military helicopter crashed in woods in South- western Germany on Wednesday, killing at least two people, German police said.

The aircraft crashed at about 6:20 p.m. local time near a motorway junction between Viernheim and Lorsch, South of Frankfurt, Hesse state police said.

The helicopter was a UH-60 Black Hawk, according to Bruce Anderson, a spokesman for U.S. Army Europe.

The spokesman said there were at least three people in the Black Hawk.

The Black Hawk is used for air assault and other military operations. It is normally designed to carry 11 combat-loaded troops.

It was not clear what had caused the crash and where the helicopter was flying to or from.
