Around 2:20 p.m. Friday, tensions between protesters and authorities escalated near 12th and K Streets NW in downtown Washington. Protesters, many in black masks with only their eyes showing, grabbed mailboxes, garbage cans and newspaper boxes and pulled them into the street. They appeared to be trying to block the streets.
At one point, a protester physically struggled with someone who looked like a member of the National Guard, each of them grabbing one side of the barricade. Others set a garbage can on fire. People climbed trees, traffic light poles and one bus shelter.
Here are some images of protesters, police and damage in the heart of the city’s business district.
