Two reports from Europe highlight the ongoing concerns of additional terror threats.  In the first report from Switzerland the Swiss authorities have arrested two Syrian males traveling in a vehicle containing trace explosives:

(Via AP) GENEVA — 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 IS who were believed to be plotting a “specific” attack in the city.

Geneva prosecutor Olivier Jornot spoke to reporters after Switzerland’s Attorney General’s office and Federal Police Office announced criminal investigations against the two Syrians on suspicion that they had violated laws on making and transporting explosives and toxic gases and a ban on links to militant groups like al-Qaida or Islamic State.

Amid concerns that the four fugitives might have accomplices, Jornot said: “No link has been established in the different cases.”  (more)
