Swiss authorities say they have arrested two people of Syrian origin on suspicion of making, hiding, and transporting explosives and toxic gas.
Switzerland's attorney general said on December 12 that criminal proceedings have been opened against the pair under a law prohibiting extremist groups such as Al-Qaeda and Islamic State (IS).
The two arrests were made in the Geneva region on December 11.
Geneva, home to the European headquarters of the United Nations, the International Committee of the Red Cross, and many banks and trading houses, has been on high alert amid fears that an IS cell was in the area.
The country’s president, Simonetta Sommaruga, said on December 11 that a "foreign authority" had provided the information about "a potential IS cell in the Geneva area."
