Tens of thousands of protesters marched from the White House to the Capitol to demand an end to the Iraq war, and at least 160 people were arrested when they jumped a barricade at the foot of the Capitol steps.
Many of the protesters were arrested without a struggle after they jumped over the waist-high barricade on Saturday. But some grew angry as police attempted to push them back using large shields. At least two people were showered with chemical spray. Protesters responded by throwing signs and chanting: "Shame on you."
The arrests came after protesters initially decided to lay down on the Capitol lawn with signs on top of their bodies to represent soldiers killed in Iraq. When police took no action, some of the protesters decided to start climbing over the barricade.
Before arriving at the Capitol lawn, the demonstrators marched holding banners and signs and saying, "What do we want? Troops out. When do we want it? Now."
Counterprotesters lined the sidewalks behind metal barricades. There were some heated shouting matches between the two sides.
