German authorities conducted raids in six northern German states on Wednesday due to concerns that left-wing radicals were planning attacks to disrupt the upcoming G8 summit in Heiligendamm next month. The federal prosecutor's office stated that around 900 security officials were involved in searches at 40 locations in Berlin, Brandenburg, Hamburg, Bremen, Schleswig-Holstein, and Lower Saxony. The office suspects individuals linked to the militant extreme-left scene of organizing a terrorist organization or being members of such an organization, with intentions to carry out arson attacks and other actions to disrupt or prevent the G8 summit. Security officials believe this group is responsible for nine minor attacks in Hamburg and three in Berlin over the past two years, including a well-known incident involving the car of deputy finance minister Thomas Mirow being set on fire and his house being vandalized. Interior Minister Wolfgang Schaeuble expressed concerns earlier this year about the possibility of left-wing extremists carrying out attacks during Germany's presidency of the G8. German Chancellor Angela Merkel will be hosting the leaders of several nations at the Heiligendamm summit, where discussions are expected to revolve around issues such as climate change and global economic coordination. Germany has not faced significant left-wing violence since the disbanding of the Red Army Faction in 1998, which had been responsible for a series of killings and kidnappings over a two-decade period.
