The Latest: Pipeline protesters won't move off private land

Law enforcement officials have asked people protesting the Dakota Access oil pipeline in southern North Dakota to vacate an encampment on private land, and the protesters said no.

Authorities with county sheriff's offices, the state Highway Patrol and the National Guard asked protesters to move off the site owned by pipeline developer Energy Transfer Partners.

Protesters are trying to halt construction of the pipeline they fear will harm cultural sites and drinking water for the Standing Rock Sioux.

Opponents hope to block completion of the 1,172-mile, $3.8 billion pipeline from North Dakota to Illinois that they fear could harm cultural sites and drinking water for the Standing Rock Reservation.

Activists protesting the Dakota Access oil pipeline in North Dakota say they believe law enforcement officers are planning to take action soon to remove them from private land owned by the pipeline company.

Investigators say private security guards with dogs who were involved in a clash with Dakota Access pipeline protesters weren't licensed to do security work in North Dakota.

The clash occurred Sept. 3, after construction crews removed topsoil from private land that protesters believe contained Native American burial and cultural sites.
