2 Syrians arrested in Geneva, traces of explosives found in car

The Geneva prosecutor says two Syrians arrested in a vehicle containing traces of explosives have not been clearly linked to four men with suspected ties to the Islamic State group who are wanted by Swiss authorities.

Prosecutor Olivier Jornot provided few new details Saturday after Swiss authorities began criminal investigations against the two Syrians on suspicion they had violated laws on making and transporting explosives and toxic gases as well as the ban on links to militant groups like al-Qaida and Islamic State.

The arrests come after authorities heightened security in Geneva on Thursday and said police were searching for at least four suspects allegedly linked to IS and believed to be plotting a “specific” attack in the city.

The threat level in Geneva has been raised to “moderate” by Swiss authorities.

Jornot says “no link has been established in the different cases”.
