Germany is on high alert after a spate of attacks since July 18 left 15 people dead – including four attackers – and dozens injured. Two assailants, a Syrian asylum seeker and a refugee from either Pakistan or Afghanistan, had links to Islamist militancy, officials say.
Interior Minister Boris Pistorius said in a statement that up to 400 police – including mobile squads and a special forces police commando – were involved in the raids on Wednesday in the Hildesheim area, which is a short drive south of Hanover.
“The German-speaking Islamic circle (DIK) in Hildesheim is a nationwide hot-spot of the radical Salafist scene that Lower Saxony security authorities have been monitoring for a long time,” the state official said.
Pistorius said the search followed months of planning and was an important step towards banning the association, which security authorities say has radicalised Muslims and encouraged them to take part in jihad in combat zones.
Numerous members of the mosque have travelled to Syria and Iraq to join Islamic State, while sermons, seminars and speeches call for “hate against non-believers,” the ministry said.
Germany has seen sharp increases in the number of ultra-conservative Islamists known as Salafists in recent years, with the total number of sympathisers now seen at 8,900, up from 7,000 at the end of 2014, German officials have said.
Security authorities say the DIK in Hildesheim is believed to have become the focal point of Salafist activities in Lower Saxony, the second-largest of Germany’s 16 states after Bavaria.
“We will not put up with Salafist associations and their backers flouting our rules and bringing our rule of law into question and convincing young people that they want to join the so-called IS,” Pistorius said.
“I’m convinced that our freedom is stronger than the inhuman ideology of the extremists,” he added.
