Three suspected members of al-Qa'ida have been arrested in Germany.
Police say they posed a "concrete and imminent danger" to the nation.
Authorities did not say whether the three had planned specific targets and offered few details, but security officials said that all three suspects were of Moroccan origin.
Two were arrested in the western German city of Düsseldorf – host of the Eurovision Song Contest next month – and one in nearby Bochum. The arrests were based on suspicion that they were planning a terror attack, police said.
