Around a dozen people gathered Sunday in front of the Bellagio fountains to raise awareness about the oil pipeline in North Dakota.
This comes as protests are underway in North Dakota against the $3.8 billion Dakota Access Pipeline. The protest turned violent after tribal officials say construction crews destroyed Native American burial and cultural sites.
Six people were bitten by security dogs, including a young child, and dozens were pepper-sprayed. The Morton County Sheriff's Office said four private security guards and two guard dogs were injured.
Hundreds of people have been gathering to join the Standing Rock Sioux Tribe's protest of the pipeline that is slated to cross the Missouri River nearby.
The protest on the Strip was being scheduled to go through 7 p.m.
