STRAUBING, Germany Clashes broke out during the night in a castle near this southern German town when police moved in to disperse an international meeting of some 600 far-right skinheads, AFP quoted police as saying Sunday. Three police officers were slightly injured when they were struck by stones thrown by the skinheads, who had arrived from across Germany, Austria, France, the Netherlands, Belgium and Switzerland, police said. Five skinheads were arrested in the fracas, during which a number of cars were damaged. The situation calmed down later in the night. While most of the right-wingers left the Bavarian castle in buses after the police action, about 100 spent the night in their cars, closely watched by police.
