HEIDELBERG, Germany - A sixth U.S. service member died Thursday evening of injuries sustained when a U.S. Army UH-60 Black Hawk helicopter attached to 1st Battalion, 214th Aviation Regiment crashed at approximately noon Thursday 22 miles southwest of Aviano, Italy.

This brings the number of deaths to six service members. Eleven U.S. service members were on board the aircraft, four U.S. soldiers as the crew and seven U.S. Air Force passengers.

The names of the victims are being withheld until notification of next of kin has been completed. When appropriate, names will be released by the individual services.

The cause of the crash is under investigation.

Deepest condolences go out to the families of the victims, said U.S. Army Europe and 7th Army officials.

This was a training flight which also afforded Airmen the opportunity to gain a better understanding of joint operations and to perform a reenlistment ceremony, officials said.
