New rules about liquids at Zurich airport exclude some bottles; incidents of aggression on Swiss trains are rising; and more news in our roundup on Thursday. New rules about liquids at Zurich airport are not all-inclusiveSince the end of June, when high-tech CT scanners went into effect at Zurich airport, bottles with up to two litres of liquids have been permitted in carry-on luggage. However, numerous passengers have complained that insulated or thermos bottles can only be taken through security when they are empty. This means that contents, including baby formula, must be emptied before going through the security check.
