Thousands of police officers provided security as a Ku Klux Klan march and rally drew about 30 robed and hooded members to the nation's capital. Forty-three counter-demonstrators were arrested and 14 people were injured.

The rally at the Capitol on Sunday was the second in as many months. More than 5,000 officers from three police departments prevented a few thousand counter-demonstrators from coming face-to-face with the Klansmen.Six protesters were treated at a local hospital for minor injuries, according to local police.

Eight police officers were hurt, most suffering minor injuries in confrontations with the counter-demonstrators, said city police spokesman Sgt. Joe Gentile. A female officer suffered a serious neck injury when she was struck by a rock, according to Ed Wilson, another police spokesman.

Gentile said the Metropolitan Police arrested 40 demonstrators. Three others were held by the U.S. Capitol Police on charges of disorderly conduct, demonstrating after revocation of a permit and disobeying the orders of a police officer, said spokesman Dan Nichols.

"We knew this was going to happen," District Police Chief Isaac Fulwood Jr. said at a news conference afterward. Referring to a federal judge who rejected a city bid to restrict the march to a shorter path, he added, "We thought that the judge erred. I thought he used poor judgment."

Several officers struck counter-demonstrators with clubs, but Fulwood said he did not believe they used excessive force. None of the Klan members was hurt.

"K-K-K, we're here to stay," shouted the Klansmen as they marched the 11-block route from the Washington Monument to the Capitol.
