Seven people were briefly taken to hospital after a suspicious package containing a white powder was opened on Thursday at Joint Base Andrews, the Maryland military installation near Washington that houses Air Force One, US media reported.
Initial HAZMAT findings and response
CNN reported that a HAZMAT team conducted preliminary tests on the unknown substance and found it not to be hazardous. Those who were transported to local hospitals were later released, although some had reported headaches, according to Fox News.
Investigation underway
Sources cited by CNN said the package also contained material described as "political propaganda." Base officials said they evacuated the affected building and an adjoining structure as a precaution. In a statement to the media, Joint Base Andrews said: "Joint Base Andrews first responders were dispatched to the scene, determined there were no immediate threats, and have turned the scene over to Office of Special Investigations."
