German prosecutors say a man arrested after the truck attack on a Berlin Christmas market has been released because there isn't sufficient evidence to tie him to the rampage.
Federal prosecutors said Tuesday that the man, a Pakistani citizen who came to Germany last year as an asylum-seeker, denied involvement in the attack that killed 12 people and injured nearly 50 others.
German Chancellor Angela Merkel said on Tuesday that "we must assume at the current time that it was a terrorist attack."
