Swiss prosecutors say they have released two Syrians taken into custody in December after finding no evidence to support suspicions they had been transporting explosives.
The two men were taken into investigative custody Dec. 11 after authorities said they found possible traces of explosives in their car at a road checkpoint in Geneva.
Federal prosecutors in Bern, the Swiss capital, said in a statement Saturday that forensics testing had failed to back up that suspicion.
The two, whose names weren't released, also were investigated for possible terrorist links but no evidence was found.
Prosecutors say one man already has left Switzerland while the other, who was traveling without valid documentation, faces deportation.
