Left-wing protesters clash with police on May 1, 2014 in Hamburg, Germany. Left-wing activists from across Germany gathered in Hamburg today to take part in demonstrations as a sign of solidarity with the residents of the Rote Flora squat and leftist cultural center. A real estate developer, who has owned the property since 2001, is seeking to rebuild the former theater into a six-storey building with a concert hall, though the Rote Flora occupants have responded with strong and sometimes violent opposition.
