US officers are taking up posts at Paris' Charles de Gaulle Airport to help identify high-risk passengers.
Officers from the US Customs and Border Protection's Immigration Advisory Program joined French airport personnel on Thursday in an advisory capacity. The US officers can make recommendations to block a passenger from boarding, but cannot make arrests themselves. The program aims to identify militants, preventing people trafficking and passport fraud. It has been expanded after an attempted militant attack by a passenger on an Amsterdam-Detroit flight last Christmas Day. US officers are already working at airports in seven other countries.
