21 Protesters Arrested Outside the Pentagon [VIDEO]

ARLINGTON, VA — Several protesters were arrested during a protest against U.S. involvement in wars abroad outside the Pentagon Monday morning.

A total of 21 protesters from multiple groups were arrested, according to Chris Layman, a spokesman for the Pentagon Force Protection Agency. They were charged with "failing to obey a lawful order," Layman said.

Specifically, the arrested protesters were attempting to block the employee entrance, he said, adding that standard procedure is to give them three warnings before arresting them.

Layman could not provide a figure on the total number of protesters, but one protest group, World Beyond War, said in a press release that there were several dozen there.

"Dozens of war protesters demonstrated at the Pentagon this morning. Most voiced their concerns from within a free speech cage," according to the statement. "Others attempted to deliver petitions and letters to the Pentagon and were arrested for their trouble and for 'Disturbing the Peace.' In fact, said World Beyond War's David Swanson, they were disturbing the wars."

The protest began at 9 a.m. outside the Pentagon near the top of the Pentagon Metro station escalators.
