Former Pink Floyd singer Roger Waters is locked in a battle with Munich’s mayor over stoking hatred of Israel.

A young German man was arrested after several people were stabbed at a train station near Munich early Tuesday, authorities said. One victim later died in a hospital and three other people were wounded.

The mayor of Munich, Dieter Reiter, said that the German city will not permit anti-Israel or pro-BDS (Boycott, Divestment and Sanctions) events to be held in municipal space.
