"You have to make priorities, check them and look at what they are doing. It is difficult. We’re doing it together with the police," the representative of the service said, adding the task of prioritizing surveillance subjects is "one of the hardest."
German intelligence and police are unable to track simultaneously the hundreds of Islamic radicals residing in the country, a representative of Germany’s domestic intelligence service told Sputnik on Friday.
On Friday, Hans Georg Maassen, the head of the intelligence agency — the Federal Office for the Protection of the Constitution — said there are about 1,100 radical Islam supporters, potentially ready to conduct attacks in Germany with at least 430 of them so dangerous that "a serious crime can be expected from them in any moment."
"The problem is that if you want to put them [Islamic radicals] under surveillance, it takes a lot of people, many of them to track just one. You cannot survey all of them at the same time 24 hours and 7 days a week," the representative of the Federal Office for the Protection of the Constitution said.
Earlier in December, the German parliament approved a military campaign against Daesh in Syria. The German campaign against Daesh is planned to continue until December 31, 2016, and is expected to cost Germany approximately $143 million and include up to 1,200 servicemen.
Russia, which has outlawed Daesh and designated it a terrorist organization, has also been conducting airstrikes against the group's positions in Syria since September 30, following a request from President Bashar Assad.
