BAD AROLSEN, Germany (Reuters) -Authorities had yet to establish a motive on Thursday for a 29-year-old German-Armenian man who rammed his car into a group of schoolchildren in Berlin, killing a teacher and leaving another fighting for his life, but said he had no known link to terrorism.

Investigators, with the help of a translator, were trying to make sense of the "at times confused statements he was making" during questioning, Berlin's mayor, Franziska Giffey, told RBB inforadio, describing a "dark day in the history of Berlin".
