BERLIN – The day after a truck plowed into a bustling Christmas market in Berlin, killing 12 people, authorities are still scrambling for a motive, and the only person arrested after the attack was released because of insufficient evidence.

German Chancellor Angela Merkel described herself as “shocked, shaken and deeply saddened” after what she said the government must assume was a “terrorist attack.”

However, no group took responsibility in the immediate aftermath.
