"[About] 12,000 people gathered at the moment at the Deichtorplatz [square]," the police said on its Twitter account, adding that the rally was held under a slogan "G20 — not welcome!"
After demonstrators started marching from the square with anti-G20 banners, the number of the event's participants had almost doubled reaching about 20,000, according to police.
The two-day summit started in Hamburg on Friday. The forum brought together not only the leaders of the major world economies, but also thousands of demonstrators protesting against the international event and globalization among other issues. Several of the anti-G20 rallies in Hamburg have turned violent. According to the local police, over 200 police officers have been injured in the clashes.
