BISMARCK, N.D. (AP) - A South Dakota tribal chairman has urged members to avoid Bismarck and Mandan in North Dakota after a clash between private security guards and people protesting against the four-state Dakota Access Pipeline.
Cheyenne River Sioux Tribal Chairman Harold Frazier said in a statement Sunday his members were among protesters pepper-sprayed by security officers and attacked by dogs at the oil pipeline construction site Saturday on private land north of the Standing Rock Sioux Reservation in North Dakota, south of Bismarck.
Tribe spokesman Steve Sitting Bear says protesters reported that six people were bitten by the dogs and at least 30 people were pepper-sprayed.
Morton County Sheriff's Office spokeswoman Donnell Preskey says four security guards and two guard dogs were injured after several hundred protesters confronted construction crews. Hundreds of people from across the country have joined the Standing Rock Sioux to protest the pipeline. Tribal leaders say workers have destroyed American Indian burial and cultural sites.
Preskey says there were no law enforcement personnel at the site when the incident occurred and that the crowd disbursed when officers arrived and no one was arrested.
North Dakota Gov. Jack Dalrymple's office Sunday urged protesters "to participate only in peaceful and lawful activities."
