 Geneva's Prosecutor Olivier Jornot told a news conference that the two Syrians had just arrived in the Swiss city and could not speak French when they were arrested on Friday. They "were stopped by Geneva police... because of the increased vigilance required from the police force," he said. The federal prosecutor's office had said in a statement earlier Saturday that the two men were arrested on suspicion of the "manufacture, concealment and transport of explosives and toxic gases" and of violating Swiss law prohibiting "groups like Al-Qaeda, Islamic State and similar organisations". The Le Temps daily on Friday cited an unnamed source close to the case as saying the Swiss had received a tip-off from US intelligence about a jihadist cell in Geneva. Armed police were deployed at sensitive locations across Geneva, which borders France and is home to the United Nations' European headquarters. But Jornot said they were not among the four men being searched as suspected jihadists planning attacks following the Paris carnage on November 13 and whose photographs have been released by the police.
– Two people from Syria were arrested on terror charges Friday in Geneva and traces of explosives were found in their vehicle, AFP reports. The arrests come after Swiss authorities received a tip from US intelligence that indicated an ISIS cell was active in Geneva, according to the BBC. ABC News reports Geneva raised its terror threat level Thursday in response to the tip. According to AFP, the arrested men have been accused of the "manufacture, concealment, and transport of explosives and toxic gases" and of supporting "groups like Al-Qaeda, Islamic State, and similar organizations." The arrests were announced as part of a "terror probe" by Swiss authorities Saturday, AFP reports. Police have been deployed around Geneva as the city remains on alert. In addition to being the UN's European headquarters, many international organizations active in Syria—including the International Organization for Migration and UN High Commissioner for Refugees—are also based in Geneva, according to ABC. The BBC reports the same source who claims US intelligence found an active ISIS cell in Geneva also states two more were identified in Chicago and Toronto.
