Los Angeles ? A white supremacist group rallied against illegal immigration in downtown Los Angeles on Saturday as hundreds of counter-protesters gathered to shout them down in a tense standoff that included several arrests, thrown rocks and police in riot gear.

Police officers stood between the white supremacists and counter-demonstrators on the south lawn of Los Angeles’ City Hall, where about 50 members of the National Socialist Movement waved American flags and swastika banners for about an hour. Five people, all of them counter-protesters, were arrested on suspicion of throwing items, police said.

The white supremacists shouted “Sieg Heil” before each of their speakers took the podium to taunt counter-protesters with racial, anti-Semitic and misogynistic epithets.
