German law enforcement agencies warned that attacks by neo-Nazi
elements "should be expected" against foreigners, Jewish institutions and "representatives of the Federal Republic of Germany,
such as politicians, public figures, and police officers," Der Spiegel said on Sunday.
The magazine said it had seen a secret report issued by the Federal Office of Criminal Investigation, dated July 2012, which warned that the attacks could come from neo-Nazi individuals or groups and may include arson attacks, possibly on refugee hostels and Jewish community buildings. The report also warned of possible homicides.
The report claims the planned attacks are a response to last year's investigation which exposed a right-wing extremist cell dubbed the National Socialist Underground,
whose members killed nine Greek and Turkish
immigrants, as well as a police officer.
The continued probe and the pressure applied on the cell may "back its members into a corner" and cause them to "want to prove their own ability to act with violence," according to the confidential report.
Der Spiegel said that in light of the report investigators are studying the case of Anders Breivik
in Norway, the right-wing extremist who was convicted of killing 77 people in July 2011.
Citing the report, the magazine said two other investigations are being conducted into the suspected founding of right-wing terrorist groups in Germany.
