Frankfurt am Main: German police on Tuesday arrested six Syrian refugees suspected of preparing a terror attack in the name of the Islamic Statemilitant group, prosecutors said.
The suspects, aged 20 to 28, were detained in dawn raids that saw some 500 police officers swoop on residences in the cities of Kassel, Essen, Hanover and Leipzig.
The men are accused of belonging to "the foreign terrorist group that calls itself the Islamic State", Christian Hartwig, a spokesman for the Frankfurt prosecutor's office, said in a statement.
"The accused are also suspected of preparing an attack on a public target in Germany using weapons or explosives," Hartwig said.
The investigators believe the men had not yet finalised their attack plan, he added.
