British rock star Kate Nash is leading the effort to support the Standing Rock Sioux tribe, environmentalists and other protesters who have been at the center of a dispute over an area slated to be used in the Dakota Access Pipeline.

She's recruited more than 100 big-name musicians, including members of Green Day, Radiohead, Pink Floyd, Death Cab for Cutie, Guns & Roses and Icona Pop, to sign a letter reiterating requests to remove pipeline construction and review the environmental impact of the project.

The crude oil pipeline would cross through the tribe's sacred grounds and waterways in North Dakota as part of its 1,200 mile route.

In the open letter, addressed to President Barack Obama, the U.S. Army Corps of Engineers and the U.S. Department of Justice, Nash wrote about unfair violence inflicted on protesters who have been camping out for months at the site.

She listed blasting water canons in below freezing temperatures, spraying mace, using rubber bullets and other tactics that have injured #NoDAPL protesters.

The letter, which Rolling Stoneprinted in full Friday, asks for an end to the violence.

"We are writing to express our shock at the treatment of the people of Standing Rock Sioux in North Dakota. We are deeply disturbed by the police actions that have been taking place, where non violent protests have been and continue to be met with extremely aggressive tactics."

"We call on the White House to deny the easement now, revoke the permits, remove the DAPL construction workers, and order a full environmental impact statement in formal consultation with impacted tribal governments," it adds. "Put an end to the violence."

In the past week the Army Corps of Engineers gave the camps a Monday deadline for protesters to leave the area or face trespassing charges and prosecution.

Although the federal agency says they will not forcibly remove anyone, this is a reversal from a statement earlier this year that stated the camps were allowed on the federal land as an expression of free speech.
