Police arrested 21 neo-Nazis Saturday at a demonstration marking the first anniversary of the death of Rudolf Hess, a key deputy to Adolf Hitler during World War II, a police spokesman said.

Eight were arrested for giving the Nazi salute and 13 for carrying objects that could be used as weapons, the spokesman said.An estimated 100 right-wing extremists attended the demonstration in the small Bavarian town of Wunsiedel, 70 miles northeast of Nuremberg, where Hess was buried in a family cemetery seven months after his Aug. 17, 1987, suicide at the four-power Spandau War Crimes Prison in West Berlin.

Hess was 93 when he died.
