Armed police officers have launched a raid on a mosque and several homes belonging to a group believed to be radicalising Muslims in Germany.

Apartments belonging to eight board members of the radical German-speaking Islamic group 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.
