According to Germany's Interior Minister Nancy Faeser, the German security authorities have the Islamist scene in Germany firmly in their sights.
"We are using all the instruments at our disposal: from intelligence monitoring to intensive investigations," the SPD politician told the Funke Mediengruppe newspapers. In the last few months alone, the authorities had struck early on several occasions to prevent attack plans.
Faeser assured that those who had fantasised about a caliphate at an Islamist demonstration in Hamburg at the end of April were also in the focus of the security authorities.
"In our constitutional state, however, we can only ban such groups if the high legal requirements are met," explained the minister.
The Muslim Interaktiv group, which has been categorised as extremist, plans to take to the streets again in Hamburg this Saturday afternoon. The rally is subject to strict conditions.
These include a ban on inciting hatred or violence and denying Israel's right to exist. A rally also organized by Muslim Interaktiv at the end of April called for a caliphate as a solution to social problems. The march had triggered nationwide outrage.
Faeser said she agreed with the strict conditions imposed by the Hamburg authorities.
"This makes it possible to intervene immediately and harshly if the demonstration aggressively calls for a caliphate in Germany and if Israel's right to exist is denied or Jews are incited," she said.
The security authorities were also keeping a very close eye on whether the ban on the terrorist organization Hamas and the Samidoun group was being violated.
