Members of the emergency services gather near to the collapsed building of the town archive of the German city of Cologne, March 3, 2009. More than 200 rescue workers rushed to the scene in the south of the city after the collapse of the multi-storey building, which German media said may have been sparked by work on an underground train line. At least one person was injured and possibly others are trapped inside, a Cologne police spokesman said, adding the cause for the collapse was still unclear. In background is Cologne Cathedral.
