Berlin  - German federal police (BKA) have warned in a secret report that the Lebanese-based Hezbollah movement has the capacity to undertake damaging attacks in Germany, the news magazine Focus reported Saturday.

The militia had the logistics "to carry out widescale attacks on physical and human targets," the weekly said in a report released ahead of publication.

The BKA is reported to number Hezbollah supporters in Germany at around 900.

Focus pointed to the case of a 29-year-old medical student at Germany's Goettingen University, who was detained in Israel last month.

It reported the man was suspected of making contact with Hezbollah supporters in Germany and of having received 20,000 dollars for espionage work. (dpa)
