Security officials say that up to 8,000 of the demonstrators will be anarchists and left-wing radicals whose main goal is to disrupt the summit. They are planning a protest on the eve of the G20 that they have dubbed “Welcome to Hell”. “The policies of the G20 have created hellish conditions in many countries around the world,” Andreas Blechschmidt, one of the organizers of the July 6 protest, told Reuters in front of the Rote Flora, which stands just a few hundred meters from the site where the leaders will meet.
