A plane was evacuated at Baltimore-Washington International Airport, and four passengers who appeared to be Muslim were searched, after someone reported seeing one of them watching what they believed to be a video from the self-proclaimed Islamic State terror group.

Three men and a woman were removed from the Spirit Airlines plane, which was about to take off to Chicago's O'Hare International Airport, when a female passenger was seen watching a video that another passenger deemed "suspicious."

"A passenger alerted a flight attendant of a passenger engaged in suspicious activity on board," a source told Reuters. The plane had not yet taken off, and returned to the gate. All passengers were evacuated

First Sergeant Jonathan Green, a spokesman for the Maryland Transportation Authority police, told Reuters that one of the four travelers were questioned and released.

Once the aircraft and all passengers luggage were cleared, the plane took off approximately three and a half hours later.
