There are reports of another standoff between state police and protesters against the Dakota Access Pipeline, where according to sources rubber and mace might have been used, with one protester being rushed to a clinic.

Protesters were allegedly trying to build a makeshift bridge on Wednesday, according to reporter Jason Patinkin on the site.

RT sources confirmed that police used mace and rubber bullets on protesters.

Late Tuesday President Barack Obama said the US Army Corps of Engineers is considering ways of rerouting the Dakota Access Pipeline amid an eight-month-long protest staged by the Standing Rock Sioux tribe.

The Standing Rock Sioux are protesting the pipeline's route due to the potential threats it poses to drinking water supplies and sacred sites. Their cause has attracted millions of dollars in support.

"My view is that there is a way for us to accommodate sacred lands of Native Americans, and I think that right now the Army Corps is examining whether there are ways to reroute this pipeline," Obama told news website NowThis on Tuesday.

Government agencies will let the situation "play out for several more weeks and determine whether or not this can be resolved in a way that I think is properly attentive to the traditions of First Americans," Obama said.

The $3.8 billion pipeline, which is being constructed by Energy Transfer Partners, would transport 470,000 barrels of crude oil from the Bakken oil field in North Dakota through three other states to a refinery near Chicago.
