Arrested Syrians not linked to ISIS

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, the Geneva prosecutor said Saturday.

The arrests of the two Syrians on Friday came amid stepped-up police patrols in Geneva.

Authorities raised the security vigilance level and announced a hunt for at least four suspects allegedly linked to Islamic State who were believed to be plotting a “specific” attack in the city.
