(KGTV) — A phony picture of an explosion at the Pentagon went viral on Twitter Monday morning.
The photo, which reportedly was generated using artificial intelligence, was reshared on a number of prominent accounts.
The resulting confusion even affected the stock market.
The S and P 500 fell 30 points when the image was believed to be real, before quickly rebounding when it was confirmed to be fake.
That's a $500 billion market swing.
The Arlington County Fire Department and the Defense Department confirmed there was no explosion.
The source of the image has not yet been determined.
