AP has the story. Sarah Karush writes:
Police have arrested about a dozen people who crossed a barricade at the entrance of the Internal Revenue Service building in Washington at the start of protests marking the fifth anniversary of the Iraq war.
Anti-war protests and vigils are planned across the country.
Dozens of people gathered at the IRS, chanting “This is a Crime Scene” and “You’re arresting the wrong people.” A crowd marched around the IRS before gathering at the entrance.
