The Swiss attorney general has opened a criminal investigation of a leading member in a Swiss Muslim organisation accused of violating a ban on jihadist groups, the attorney general's office said on Saturday.
Switzerland is on high alert after Islamist militants killed 130 people in Paris in November. A week ago, two Syrians were arrested near the French border on suspicion of having links to Islamic State. Traces of explosives were found in their car.
The attorney general's office did not name the accused, but the Islamic Central Council, which says it is the largest Muslim organisation in Switzerland, identified him as the German head of its multimedia department, Naim Cherni. He was either 23 or 24 years old, the spokeswoman said.
