The intelligence agency chief said that such often come from a conservative Islamic background
Hans-Georg Maassen, Head of Germany's Federal Office for the Protection of the Constitution, said on Sunday in Berlin that there are more than 340 incidences on record.
``But these are the only the cases known to us. Presumably there are even more.’’
Maassen said workers at German refugee centres have already been made aware of the situation.
``It worries us that Salafists and other Islamists are promoting their cause in asylum centres.
``We know that there are very many young men of the Sunni denomination among asylum seekers,’’ he said.
The intelligence agency chief said that such often come from a conservative Islamic background and want to go to an Arabic-speaking mosque every Friday.
Maassen also noted that there were also numerous radical Salafist mosques in Germany.
He said that the Arabic-speaking mosques in Germany are not regulated and from the perspective of the state, there is very little the agency can influence.
Maassen said that Islamist-motivated attacks had also taken place before a recent spate of violence in the past month in Germany, and that a policeman in the city of Hanover as well as a Sikh temple in Essen had also been targeted.
``The lesson to learn from this is that we should not concentrate only on Islamic State, which may be sending terrorist units to Europe, as with Paris or Brussels.
``Instead it could be that individuals that are radicalized on their own or are given orders,’’ he said.
