United States

The FBI has posted a video showing an American appearing in Islamic State propaganda, in an attempt to identify him. Mohammed Hamzah Khan, a US citizen from Bolingbrook, Ill., was arrested on Oct. 4 at O’Hare Airport as he was trying to travel to Syria to join the Islamic State. US intelligence officials said that recent US airstrikes in Syria against al Qaeda’s “Khorasan group” cell have not disrupted the cell’s operations. At least one cell member, French jihadist David Drugeon, is thought to have escaped the strikes. The Justice Department has already charged 10 people this year for seeking to join terrorist groups abroad, a marked increase over the five US prosecutions on similar charges from 2011 to 2013.
