German police said at least 12 people were killed and at least 48 people were injured after a truck barreled into a packed Christmas market in Berlin. The truck was driven into the crowd on a sidewalk, bringing down Christmas lights and smashing stalls at the festive market near the Gedaechtniskirche, or Memorial Church, in western Berlin. The black truck had Polish license plates. Dozens of ambulances and hundreds of rescue workers were on the scene, NPR's Soraya Sarhaddi Nelson reported.
