Armed police officers have launched a raid on a mosque and several homes belonging to a group believed to be radicalizing Muslims in Germany.
Apartments belonging to eight board members of the radical German-speaking Islamic group DIK were searched by officers in Hildesheim, Lower Saxony.
It comes as part of a crackdown on the group, which is thought to have been encouraging people to travel to Syria and Iraq to join ISIS.
The group ran sermons, seminars and lectures entitled 'the hatred of infidels', according to German media.
The raid on Wednesday night involved up to 400 volunteer staff, as well as a special police task force.
'The DIK in Hildesheim is a nationwide hot spot of radical Muslims that we have been watching for a long time,' said Lower Saxony Interior Minister Boris Pistorius.
'After months of preparation, we have taken an important step to end the association.'
Several people who attended the mosque are believed to have travelled to join the terror group.
It comes after 10 days of terror in Germany, as lone wolf attackers have unleashed assaults across the country.
Five people were injured on a train in Wurzburg on July 18, when a 17-year-old asylum seeker wielding an axe and a knife went on a rampage.
The attacker, Riaz Khan Ahmadzai, seriously injured four members of a family of holidaymakers from Hong Kong as well as a German passer-by.
Nine people were killed in Munich on July 22, by a German-Iranian gunman who had no Islamist ties but was obsessed with mass killings.
Some 15 people were injured in Ansbach on July 24 when a Syrian attacker blew himself up outside a music festival packed with some 2,500 revellers. The attack was claimed by ISIS.
Meanwhile in an attack yesterday in France a priest was brutally slain by two knife-wielding attackers in an assault that was also claimed by ISIS.
The two attackers burst into the church in Saint-Etienne-du-Rouvray and slit the throat of Father Jacques Hamel before giving a sermon in Arabic, according to witnesses.
