BERLIN, July 3 (Xinhua) -- A German administrative court has confirmed measures by police in Hamburg to prevent protestors at the G20 summit from establishing a permanent camp on Monday.
Previously, the organizer of the "Anticapitalist camp" had sought to appeal a police ban on sleeping tents, showers and kitchens.
A police spokesperson wrote on Twitter that the Hamburg court ruled accordingly and added that "no overnight stays will be tolerated."
Police had clashed with protestors at the campsite in southeast Hamburg on Sunday night as authorities removed 11 tents. According to the police, residents offered resistance, leading to the arrest of one individual and the use of pepper spray.
A series of protests against the G20 summit, scheduled for July 7 and 8, attracted more than 4,000 people on Sunday and included a procession of boats and rafts on the Binnenalster lake in the city center.
German authorities expect up to 100,000 people to join protests at the biggest upcoming rally on Saturday. German Minister of Justice Heiko Maas has warned against violence at rallies, while police have told press they are concerned about acts of sabotage at Hamburg's harbor and other infrastructure.
A range of demonstrations has been organized to call on G20 leaders to act more decisively on climate change and global inequality. So far, the majority of protests has been peaceful.
German police officers are out in force in Hamburg to ensure security at the summit. Police have intensified controls at the German-Danish border to identify potentially violent protestors.
Despite an official ban, members of an association of activists known as the initiative "BlockG20" have announced their intention to block access roads for diplomatic convoys and enter the 38 sq km "blue zone" which has been cordoned off from the public by security forces.
Hamburg's administrative court had previously confirmed the ban of two demonstrations in the restricted area.
