A man has been seriously injured in a stabbing at Berlin’s Holocaust memorial, the Tagesspiegel newspaper reports, adding that police have sealed off the site in the city center and are carrying out a search.

Berlin police tell the newspaper that the man had been injured by a sharp object and transported by the fire brigade to a hospital. Tagesspiegel says the attack took place on the northern side of the sprawling Holocaust monument, near the US Embassy.
