The Jet Blue terminal at JFK Airport has been evacuated over reported security concerns.

Groups of passengers are currently huddled outside the Jet Blue terminal at JFK Airport after being evacuated by security officials.

Several security guards told Fox News' Geraldo that "suspicious devices" were found. Two flight captains are claiming grenades were found in the 'bag room'.

The Port Authority of New York began investigating around 8 am EST.

It was clear that authorities felt evacuation was urgent and have moved all evacuated passengers even further from the terminal building.

Update: It appears authorities have handled the situation. Passengers were allowed to enter the terminal shortly after the news of suspicious devices initially broke.
