Berlin police say vandals have daubed swastikas on some of the slabs that make up the German capital's Holocaust memorial. A police statement says security guards discovered the swastikas and anti-Semitic slogans on 12 slabs Saturday lunchtime. Authorities ordered the graffiti's swift removal. The memorial to the Holocaust's 6 million Jewish victims consists of a field of 2,700 gray slabs situated close to the capital's Brandenburg Gate. It opened to the public in 2005 and is freely accessible around the clock. Similar vandalism has occurred on several previous occasions.
