The police in Geneva, Switzerland are hunting for at least four Islamic State (ISIS) suspects possibly involved directly in the Nov. 13 terrorist attacks in Paris as the Swiss government raised its alert level and intensified collaboration with other European nations facing threats from the terror group.

The Swiss government said armed policemen were deployed at sensitive locations across Geneva in search for the suspects, all men, whose photos were published in a Swiss paper. The CIA recently uncovered a new terrorist plot by these men, prompting authorities to immediately launch a manhunt, CBN News reported.

The operation was launched after French authorities identified the third member of an Islamist cell that stormed the Bataclan concert hall in Paris, killing 90 people, as 23-year old French national Foued Mohamed-Aggad.

"The Geneva police, on the basis of this information, have increased their level of vigilance and reinforced the number of police agents on the ground,'' the Geneva department of security said in a statement, the International Business Times reported.

The French government said it took forensics almost a month of analysis to put a name to the remains of the suicide bomber who participated in the slaughter of 130 people in Paris.

Also, police in Paris have shut down a third mosque and seized ISIS propaganda and ammunition stored in the facility, Agence France Presse reported. Police also found Islamic extremist documents at the homes of the mosque leaders.

Moreover, the Swiss government has confirmed the arrest of two Syrians on Friday who were caught ''transporting explosives.''

Swiss media reported that the two men had been arrested in the Geneva region and that traces of explosives were found in their car.

The men were accused of the "manufacture, concealment and transport of explosives and toxic gases," the federal prosecutor's office said in a statement.

They are also under suspicion of violating Swiss law prohibiting "groups like Al-Qaeda, Islamic State and similar organisations,'' according to reports.

Meanwhile, a key committee of EU lawmakers has approved a new plan to track extremist fighters, paving the way for the long-delayed system to be approved early next year.

The European Parliament Civil Liberties committee has voted overwhelmingly Thursday to approve the airline passenger information system.
