Berlin police use water cannons to help people cool down during heatwave

Berlin police have resorted to using water cannons to help people cool down amid a severe heatwave. Usually employed to disperse crowds and suppress riots, two water cannons are now patrolling the city to spray water on locals and tourists. On Saturday, the police first sprayed water at the Brandenburg Gate, then moved to the Reichstag building, Potsdamer Platz, the Red Town Hall, and Mauerpark. Within that single day, the police had already used 9,000 liters of water. The move follows Friday's record temperature of 41.3 degrees Celsius, the highest ever measured in Germany, according to the German Weather Service. Due to the extreme heat, German railway company Deutsche Bahn and other rail operators are advising against making non-urgent trips on long-distance and regional routes.
