Anti-Nazi protesters clash with German police

Four police officers were injured in a clash Saturday with anti-Nazi protesters in the northern city of Bremen, police said. Some 3,500 anti-Nazi demonstrators showed up to protest a march of about 100 members of the extreme-right NPD party, and an estimated 2,500 police were on hand to keep the peace. Around 300 of the demonstrators overran a police blockade, and four officers suffered minor injuries, police said. An unknown number of the protesters were arrested.
