The U.S. Air Force said it has detonated the last known explosives on a former bombing range on the Pine Ridge Indian Reservation.

The Rapid City Journal reports ( ) that contractors with the 28th Civil Engineering Squadron and Native American Engineering blew up the final four bombs known to exist on the 2,486-acre bombing range on Oct. 3.

The range dates to World War II, when it was used to train bomber pilots starting in 1942.

Unexploded munitions on the bombing range have left the land dangerous to use.

The Oglala Sioux Tribe signed an agreement with the 28th Bomb Wing at Ellsworth Air Force Base in 2008 to begin removing the explosives.
