Summary: Germany's Christmas markets are world-renowned. But an attack in Berlin on Monday changed one from a scene of holiday cheer, to one of death and destruction. The truck rammed into crowds and stalls. 12 people were killed, and 48 injured. And police scrambled to find the person responsible. They arrested a Pakistani refugee, but released him through lack of evidence. Then they began to search for a Tunisian man whose ID was found in the truck. ISIL has claimed the attack, but its role remains unclear and unverified. So what are the political and security ramifications from this latest atrocity?
