Christmas market truck crash was deliberate-Berlin police

Berlin (CNN)It was a quintessential Christmas scene: trees strung with lights, vendors serving candied fruit and waffles, the smell of mulled wine wafting through the cold December air.

Happy shoppers milled around buying snacks and gifts in the final days before the holiday.

All that was torn apart at 8 p.m local time on Monday as a huge black truck hauling 25-tonnes of steel plowed into the crowd in central Berlin, killing at least 12 people and injuring dozens more.

Berlin police said the crash was intentional and is being investigated as a "presumed terrorist attack."
