German media say investigations are underway about the role of nearly a dozen Iran IRGC-linked people who are accused of launching attacks on Jewish centers.

Die Welt daily wrote Thursday that Iran’s Revolutionary Gurad manages such operations outside of Iran by hiring criminals.

Police has now launched an investigation to find out more about a terrorist cell in North Rhine-Westphalia, said Welt, adding that one of the suspects had been in radical circles for some time.

Germany and the European Union are discussing the listing of the IRGC as a terrorist organization for its role in violence on protesters in Iran.

In November, an unknown person fired several times at the door of a synagogue in downtown Essen west of Germany.

Nobody got hurt, but the investigators assume the act was part of a series of anti-Semitic attacks probably launched by a cell of terrorists managed by the IRGC, the report said.

Last month, a German TV channel reported the country's security institutions believe the Revolutionary Guard is behind the attacks on Jewish centers in the country.

On November 18, a German-Iranian was detained on suspicion of committing arson at a synagogue in the city of Bochum in Germany.

Local police suspected that the man is connected to Ramin Yektaparast, the founder of the Hell’s Angels group in the city of Mönchengladbach.

German Media reported Yektaparast fled to Iran last year to escape trial for the brutal murder of another member of the gang in 2014.

The suspect might also have been responsible for the attack on the old synagogue in the city of Essen, said German officials.
