White supremacists clashed with an angry crowd outside Faneuil Hall (search), where Holocaust survivors and their families were commemorating the 60th anniversary of the liberation of Nazi concentration camps.

Two people were arrested during Sunday's confrontation in downtown Boston, officer John Boyle said.

Inside the historic meeting house, survivors, their children, and grandchildren lit white candles to commemorate the estimated 6 million Jews killed by the Nazis during World War II.

Germany's consul-general to New England, Wolfgang Vorwerk (search), spoke of his country's role in the massacre.

Ten to 15 members of the Arkansas-based group White Revolution (search) arrived for their scheduled demonstration and were escorted by hundreds of police officers on foot, motorcycle and horseback to a designated protest area across the street.

Officers, many in riot gear, formed a barricade between the protesters and about 100 people who angrily shouted at them to leave Boston.

At one point, the crowd opposing the white supremacists surged forward, causing police to use their batons to keep them at bay.

A scuffle arose outside the protest pen when Shireen Chambers, 36, of Dorchester, allegedly struck Jerome Higins, 25, of Everett.

Police said Higins, who is black, retaliated by spitting in the face of Chambers, who is white, and hitting her with a sign. Chambers yelled racist epithets as she was dragged away by police. Boyle said at least one officer was injured while attempting to arrest Chambers.

Both were charged with disturbing the peace and were scheduled to be arraigned Monday in Boston Municipal Court.

Gov. Mitt Romney, who attended the Faneuil Hall event, said he was disgusted by the presence of the white supremacists.

"Today of all days, to have white supremacists come here from Arkansas, is most disappointing," he said. "I wish they'd go back home where the came from and bury themselves under the rocks that they crawled out from."
