Fox is reporting a threat saying the Eiffel Tower would be blown up at 5pm Paris time today. That was about 55 minutes ago. The Tower was evacuated (approximately 4000 people moved elsewhere). Authorities are still investigating. Megyn Kelly has just said that a “suspicious package” was found, but no other details. Updates when available.
There were similar threats in Feburary 2011 and September 2010, both causing the evacuation of the iconic tourist favorite.
