Native American tribes mobilize against proposed North Dakota oil pipeline

About 200 people rode on horseback to protest against pipeline that encroaches on tribal lands and could pollute Missouri river: 'We're looking out for all people'

Dozens of tribal members from several Native American nations took to horseback on Friday to protest against the proposed construction of an oil pipeline which would cross the Missouri river just yards from tribal lands in North Dakota.

The group of tribal members, which numbered around 200, according to a tribal spokesman, said they were worried that the Dakota Access Pipeline, proposed by a subsidiary of the Dallas, Texas-based Energy Transfer Partners, would lead to contamination of the river. The proposed route also passes through lands of historical significance to the Standing Rock Lakota Sioux Nation, including burial grounds.
