Intersections in Washington, D.C. were blocked on Monday morning causing delays as environmental activists participated in Shut Down DC, a protest that is “loosely associated with the Metro D.C. chapter of the Democratic Socialists of American and Black Lives Matter D.C.,” according to CBS News. Hundreds of people marched in the streets, while a handful of others chained themselves to a sailboat to paralyze traffic at Independence Avenue and 12th.

A spokesperson for Shut Down D.C., Mike Golash, said, “We hope with by our actions on Monday, we can raise public awareness of this issue and understand it’s just not going to be taken as business as usual, that we need some drastic action on climate change issues in the relatively near future.”

Twenty-six protesters were arrested for “unlawful demonstration activities” after blocking key intersections for hours around the nation’s Capitol.

Russel Gray with the group, Extinction Rebeliion, told reporters, “We’re here to disrupt business as usual. We feel that’s our only recourse.” He added, “as long as they’re thinking about climate change.”
