4 teenagers suspected of planning an Islamic extremist attack arrested in Germany

German authorities said four teenagers were arrested on Friday after being suspected of planning an Islamic extremist attack; a court issued warrants for them over the Easter weekend.

A fourth suspect, a 16-year-old boy, was arrested in the southwestern state of Baden-Wuerttemberg, German news agency dpa reported.

The three detained in western Germany are suspected of having declared themselves prepared to carry out an "Islamist-motivated terror attack" and planning such an attack, prosecutors said in a statement. They didn't specify how advanced the plans were, and said they couldn't give further details because of the suspects' young age and the ongoing investigation.
