Red alert in the Pentagon on Friday evening, when a woman threw up in a parking lot, later revealing to bystanders that she had recently traveled to Africa.

The woman felt unwell as soon as she disembarked from a bus which was transferring her to an award ceremony of high-ranking Marines.

According to information the woman is not an employee of the US Pentagon, while it is also unknown where she had traveled and whether she suffers from fever.

The point in which the incident occurred as well as one of the Pentagon’s gates have been “Sealed off for protection but also so that the investigation can proceed”.

After the departure of the woman, the bus travelled forward towards the place of the ceremony, but was immobilized by authorities. The status of the rest of the passengers is still unclear.
