Dakota Pipeline: What's behind the stand-off? Dakota Pipeline: What's behind the controversy?
(about 1 month later)
Activists around the globe have been supporting protesters who have been demonstrating in North Dakota against the Dakota Access pipeline. Activists around the globe celebrated after the Army Corps of Engineers announced it will suspend work on the controversial Dakota Access Pipeline and consider rerouting the project.
What is behind the months of confrontation between police and protesters? Members of the Standing Rock Sioux Tribe and their supporters have protested against the pipeline at a North Dakota site for months, arguing the multi-billion dollar project would contaminate drinking water and damage sacred burial sites.
Though the decision marked a major victory for Native Americans and protesters, the fight may not be over just yet.
The temporary halt comes more than a month before President-elect Donald Trump, who supports the pipeline, takes office, which means he could reverse the decision.
As the fate of the project hangs in the balance, here is a look at back at the controversy behind it.
What is the Dakota Access pipeline?What is the Dakota Access pipeline?
The $3.7bn (£2.8bn) pipeline is projected to be nearly 1,200 miles (1,900km) long and will transport some 470,000 barrels of crude oil a day from North Dakota to a terminal in Illinois where it can be shipped to refineries. The $3.7bn (£2.8bn) pipeline is planned at nearly 1,200 miles (1,900km) long and will transport some 470,000 barrels of crude oil a day across four states, from North Dakota to a terminal in Illinois, where it can be shipped to refineries.
The pipeline will provide a more cost-effective, efficient means of transporting crude, rather than shipping barrels by train. The project, built by a subsidiary of Texas-based company Energy Transport Partners, will also increase profit margins for oil companies while crude prices are low.

The Sioux Native American people of Standing Rock argue the pipeline has unearthed and will go on to disturb various ancestral sites, including stone circles and sacred ground, if it is built. The sites are technically just north of the tribe's reservation but the Sioux say the government took this land from them illegally in a series of treaties in the 1850s and 1860s.

The tribe also say the pipeline could leak and contaminate their drinking water. It is projected to run under the Missouri river, just north of their reservation. The Sioux started protesting in April, setting up Sacred Stone spiritual camp near the river.

Although the vast majority of Dakota Access oil pipeline has been built, the section closest to the Standing Rock Sioux reservation is still awaiting federal permits and approval.

More than 200 Native American tribes have pledged their support to the movement.

Several actors including Shailene Woodley and Mark Ruffalo, and Green Party presidential candidate Jill Stein, have also rallied alongside protesters. Oceti Sakowin Camp has been home to an estimated 4,000 people who travelled to the site to join in the demonstrations.

Hundreds of US military veterans joined the activists last week. The campaigners have endured bitter temperatures and had been ordered to leave the area by Monday.

Last week, a Colorado woman fired three shots in the direction of police as officers sought to forcibly remove protesters camped on private property. The woman was arrested and has been charged with attempted murder. Police deployed at the protests have also been accused of beating peaceful demonstrators while local law enforcement have characterised them as rioters and the protests as unlawful.

On 25 November the US Army Corps of Engineers issued a letter calling for the Oceti Sakowin camp, which sits on federally owned land, to be evacuated by 5 December.
This was followed by a similar evacuation order from the governor of North Dakota, citing harsh weather conditions.

Police have been criticised for using excessive force, including spraying crowds with pepper spray and firing sound cannons, bean bag rounds and rubber bullets.

During mass arrests last week, police held protesters in temporary cages made of chain-link, which activists equated to "dog kennels". The United Nations Human Rights office has criticised local law enforcement and Dakota Access LLC security staff for committing abuses against indigenous protesters, issuing a statement on 15 November.
In September, a private security firm hired by the pipeline set attack dogs on protesters. The dog handlers could face criminal charges after a local investigation found the firm was unlicensed.

The local Morten County police are being sued for excess force by a number of camp residents.
They deny any violations, and have repeatedly accused the self proclaimed "water protectors" of acting illegally.
Who would the pipeline benefit?Who would the pipeline benefit?
The pipeline would benefit oil companies, shareholders and local governments. Dakota Access says the project will create between 8,000-12,000 jobs and will generate $55m in annual property taxes.

The project could also be advantageous to Republican presidential candidate Donald Trump. He owns shares in Energy Transfer Partners and the company's chief executive officer donated to his campaign. The project could also be advantageous to President-elect Donald Trump, who has had stocks in Texas-based Energy Transfer Partners, the Dakota Access builder, and Phillips 66, which owns one-quarter of the pipeline.
Mr Trump, who supports the project, denies his policy is based on any financial interest.
Campaign finance records also show that Kelcy Warren, the CEO of Energy Transfer Partners, donated more than $100,000 (£80,437) to Mr Trump's presidential campaign.
Farmers could also benefit. North Dakota's crude oil is currently shipped out by train which has caused congestion and rail delays, slowing the shipment of grain and increasing grain prices.Farmers could also benefit.

Native American tribes by law govern themselves. Tribes also enjoy a "government-to-government" relationship with federal authorities, protected by the US Constitution. The Sioux say these provisions were ignored in the pipeline construction.Native American tribes by law govern themselves.

In September the federal government temporarily blocked pipeline construction under the Missouri, close to the Standing Rock Reservation. Although this ruling is binding until further notice, construction elsewhere along the pipeline's route is not prohibited and has continued.In September the federal government temporarily blocked pipeline construction under the Missouri, close to the Standing Rock Reservation.

But on Wednesday, in an interview with US news site NowThis, President Barack Obama said there were "ways to reroute this pipeline". What happens now?
"My view is that there is a way for us to accommodate sacred lands of Native Americans. This can be resolved in a way that I think is properly attentive to the traditions of First Americans. The Army Corps of Engineers has said it will not grant a permit to allow the pipeline to cross under the lake until it explores alternate routes.
"I think right now the Army Corps is examining whether there are ways to reroute this pipeline in a way." The corps' said the best way to reroute the project would be through a lengthy environmental review, which could take months or years.
Following Mr Obama's statement, Energy Transfer Partners spokeswoman Vicki Granado said in a statement: "We are not aware that any consideration is being given to a reroute, and we remain confident we will receive our easement in a timely fashion." The future of the pipeline, however, hinges on whether the Trump administration will allow the corps to proceed with the review or allow the completion of the original route.
As for protesters, Standing Rock Sioux Chairman Dave Archambault asked non-Sioux protesters to return home after Sunday's announcement.
"I'm asking them to go. Their presence will only cause the environment to be unsafe," he said.
But some activists are planning to stick around.
"We know that these prayers are powerful…we have to be ready, though," said activist Tom Goldtooth, of the Indigenous Environmental Network.
"We're going to accept this as a victory. But this is one battle in the broader war."
