Colorado teenager charged with attempting to join ISIS

A Colorado teenager has been charged with providing material support to ISIS, the Justice Department said Tuesday.

Acting on a tip from a social media company, the FBI encountered Humzah Mashkoor when he was 16 years old, and just under a year later, they arrested him for allegedly attempting to board a flight in Denver to join ISIS, the Justice Department said in its criminal complaint.

Undercover FBI agents soon began communicating with Mashkoor, who used the social media name “Humzah Afghan,” the complaint said.
