Around 20,000 police officers from all of Germany's 16 states have been deployed on the streets of Hamburg to help contain
protests against the G20 summit. They will be facing off against up to 100,000 protesters, including an estimated 8,000 who police say are prepared to use violence.
Dozens of police were injured in clashes on Thursday (6 July) as protesters damaged cars, set other objects ablaze and threw bottles in clashes that lasted until midnight. Police said that at least 76 officers were hurt, one of whom had to be taken to a hospital with an eye injury after a firework exploded in front of him. Officers repeatedly used water cannons, as well as pepper spray and batons, amid the clashes with violent protesters.
