Police storm Berlin's former airport used as refugee home

German magazine Focus said on Tuesday that police special forces were storming a hangar at Berlin's defunct Tempelhof airport, which now houses a refugee accommodation center.

On Monday evening a truck plowed into a crowd at a Berlin Christmas market, killing 12 people and injuring 48 others. Police say they suspect it was a terrorist attack.

German media cited local security sources as saying that there was evidence suggesting the arrested suspect was from Afghanistan or Pakistan and had entered Germany as a refugee.

Neither police nor prosecutors were immediately available for comment.
