The Associated Press reports new laws make it easier to seize passports. Suspected fighters are plucked from planes. Authorities block finances and shut down radical mosques. And behind the scenes, Silicon Valley firms are under increasing pressure to wipe extremist content from websites as Western intelligence agencies explore new technologies to identify returning fighters at the border. Governments from France to Indonesia have launched urgent drives to cut off one of the Islamic State group's biggest sources of strength: foreign fighters. At the heart of the drive is mounting concern that the organization is training the next generation of international terrorists. Those fears have gained urgency from the group's horrific methods: A British militant is suspected of beheading two American journalists, and a Frenchman who fought with the Islamic State group is accused in a deadly attack on a Jewish museum in Belgium.
