Islamic extremists may be plotting attacks in Germany, according to the head of the country's federal crime office.
The security chief believes that some 50 aspiring militants from Germany have been trained in camps run by al Qaida and the Taliban in Afghanistan and Pakistan.
In interviews with the German media, Joerg Ziercke, head of Germany's FBI equivalent, said a small number of the newly trained militants had already returned to Germany and are among some 100 suspected extremists under investigation.
``In light of statements from al Qaida we are certain that a decision has been made to conduct attacks in Germany,'' Mr Ziercke was quoted as saying in the interview.
Mr Ziercke said the camps also share connections to an Islamic Jihad Union cell - with links to al Qaida - accused of plotting to attack US and other facilities in Germany last September.
