Officials say German police carried out raids in three states searching for suspected supporters of a terror cell whose plans to attack U.S. targets in Germany were foiled last year.

Federal prosecutors' spokesman Frank Wallenta says police made no arrests during Thursday's raids on the residences of several people suspected of acquiring detonators for three alleged terror plotters.

The suspected plotters are now on trial. They are alleged to have operated as a German cell of the radical Islamic Jihad Union.

Wallenta declined to say Saturday where the raids had been carried out. Germany's Bild daily says they were in Baden-Wuerttemberg, Rhineland-Palatinate and Lower Saxony.
