The documents that fell into hands of the Federal Criminal Police Office contained personal and professional information on extremists who left Germany and went to the Middle East to wage jihad.
The documents revealed the names and surnames of the militants, their aliases within the organization, their address in Germany, information about their families and relatives, religious education and their "experience of jihad."
According to the Minister of Internal Affairs of Germany, Thomas de Maiziere, the documents will contribute to a more efficient and faster investigation into Daesh terrorists as well as better understanding of the group's structure.
According to official data, over 800 Germans have travelled to the Middle East to join Daesh and wage jihad. About 130 of them have been killed during fighting, while more than 250 have returned back to Germany and now pose a serious threat to the country's security.
