German police arrested a suspect in the stabbing on Friday evening at Berlin's Holocaust memorial that seriously injured a man two days before a watershed national election.

A 19-year-old Syrian man suspected of stabbing a Spanish tourist at Berlin's Holocaust Memorial had planned for several weeks to kill Jewish people, Berlin police believe.
