German authorities conducted raids in six northern German states on Wednesday in response to concerns that left-wing radicals were planning attacks to disrupt the upcoming G8 summit in Heiligendamm next month, according to prosecutors. The federal prosecutor's office stated that 900 security officials were involved in searches of 40 locations in Berlin, Brandenburg, Hamburg, Bremen, Schleswig-Holstein, and Lower Saxony. The office suspects individuals in the militant extreme-left scene of founding a terrorist organization or being members of such an organization, with plans for arson attacks and other actions to disrupt or prevent the G8 summit. German security officials believe this group may be responsible for several attacks in Hamburg and Berlin over the past two years, including an incident involving the car of deputy finance minister Thomas Mirow being set on fire and his house being vandalized. Earlier this year, Interior Minister Wolfgang Schaeuble issued a warning about the possibility of left-wing extremists carrying out attacks during Germany's presidency of the Group of Eight (G8) club of industrialised nations. German Chancellor Angela Merkel is set to host leaders from Britain, Canada, France, Italy, Japan, Russia, and the United States at the Heiligendamm summit, where discussions are expected to include topics such as climate change and global economic coordination. Despite this warning, Germany has not seen any significant left-wing violence since the disbanding of the Red Army Faction (RAF) in 1998, which was known for its campaign of killings and kidnappings over a period of two decades.
