German police: at least 4 severely injured in gym attack

Several people have been injured in an attack at a gym in the western German city of Duisburg. Police said a large number of officers were at the scene of the attack, right across from the city hall.

Several victims were taken to a hospital, while investigators searched the gym. Duisburg has about 500,000 residents and is located at the junction of the Rhine and Ruhr rivers. It used to be famous for its coal mining and steel production, but has in recent decades been plagued by high unemployment and poverty.
