Geneva: Swiss federal prosecutors said on Saturday they had opened criminal proceedings against a board member of Switzerland’s largest Islamic organisation accused of propaganda for jihadist groups, including Al Qaida.

The office of Switzerland’s attorney-general said in a statement it had “opened a criminal proceeding against a member of the Board of Directors of the Islamic Central Council of Switzerland (ICCS), as well as against persons unknown,” for violating “the prohibition of groups like Al Qaida, Islamic State [Daesh] and similar organisations.”

The German citizen is suspected of creating “for propaganda purposes” a video from a trip into parts of war-ravaged Syria, “without having explicitly distanced himself from Al Qaida activities” in the country, the statement said.

The man, who was not identified, had, among other things, interviewed “a senior member of the jihad umbrella organisation Jaysh Al Fath (Army of Conquest), of which the Syrian Al Qaida branch Jabhat Al Nusra (Support Front) is also a member,” it pointed out.

ICCS could not be immediately reached for comment.

The announcement on Saturday came a day after the Swiss government said it was significantly boosting the wealthy Alpine nation’s counter-terrorism forces, amid a heightened security alert in the wake of the November 13 attacks in Paris that left 130 dead.

Authorities in Geneva have since last week been searching for possible extremists with links to Daesh group, with reports that US intelligence had identified a jihadist cell in the city.

In what appeared to be a separate case, two Syrians were arrested in Geneva last week after traces of explosives were found in their car.

The attorney-general’s office said Saturday that the criminal proceedings against the ICCS member were opened on December 9.

The move shows “the rigorous prosecution brought against all persons in Switzerland who attempt to take part in jihad-motivated terrorism, or who support this by means of propaganda,” it said.

It also pointed out that it was currently in the middle of 46 criminal proceedings “in conjunction with the topic of jihad-motivated terrorism,” adding that most of these cases were linked to “suspected propaganda support of terrorist organisations.”

The attorney-general’s office highlighted that in October it had filed charges against four Iraqis accused of “preparing a terrorist attack”.
