ROME, Italy (CNN) -- A sixth U.S. service member died Friday from injuries sustained when a Black Hawk helicopter crashed in northeastern Italy on Thursday, the U.S. military in Europe said.
The helicopter, carrying 11 U.S. military personnel, crashed Thursday afternoon about 22 miles from Aviano, Italy. Four people were killed and seven were injured in the crash, and two of the injured later died, the U.S. military said.
Treviso fire officials said one of the dead was a woman, and said no one on the ground was hurt.
The U.S. military said the helicopter was an Army H-60 Black Hawk attached to the 1st Battalion, 214th Aviation Regiment.
The military was not releasing the names of those killed, pending notification of the victims' families.
Police and fire officials said the craft crashed in an open area near the Piave River north of Treviso, between the towns of Maserata Sul Piave and Santa Lucia Di Piave. Watch scenes of the crash site in northern Italy »

Italy's ANSA news agency said the helicopter crashed near the bridge of a major highway and the road was closed as a precaution.
ANSA said the helicopter had taken off from Aviano Air Base, but fire authorities could not confirm whether it was leaving or returning to the base.
The Black Hawk is considered the workhorse of the military's helicopter fleet. It is used in missions in Iraq and Afghanistan to carry troops and equipment.
The military has employed Black Hawks for about three decades. The helicopter's first combat mission was about 25 years ago. E-mail to a friend
