SIOUX FALLS, S.D. (AP) – Two American Indian tribes in South Dakota have agreed to purchase 40 acres of land near the Wounded Knee National Historic Landmark on the Pine Ridge Indian Reservation.

The Oglala Sioux tribe will pay $255,000 and the Cheyenne River Sioux tribe will pay $245,000 for the site. The agreement ends a decades-long dispute over land that is the site of the Wounded Knee massacre of 1890 in which hundreds of Lakota men, women and children were killed by U.S. soldiers. Victims were buried in a mass grave in a nearby Catholic cemetery.
