In Germany, the number of coronavirus infections has soared. The country's leading public health institute is warning that people are letting down their guard and not observing social distancing measures. Ironic then, that Berlin has seen its biggest demonstration against coronavirus restrictions.Thousands of people gathered in the German capital's central Tiergarten park for a mass rally demanding an end to all virus-related restrictions. Conspiracy theorists, anti-vaxxers and right-wing extremists from across the country are among those attending. It comes as Germany braces for a potential second wave of the coronavirus.
