"Qamar and FBI confidential witness discussed ISIL’s [Daesh] need of photos of possible targets in and around Washington, DC, for use in a video that ISIL was purportedly making to encourage lone wolf attacks in the Washington, DC area," the statement said.
Qamar and the FBI witness met twice last month to photograph a list of targets for the Daesh video, according to the statement.
Additionally, the Justice Department said Qamar tried to join Daesh in 2014, but his parents confiscated his passport and threatened to alert US law enforcement.
Qamar is charged with attempting to provide material support and resources to a designated foreign terrorist organization. He faces up to 20 years in prison if convicted.
