New footage shows the chaotic scene inside a Florida airport after a gunman opened fire in the baggage claim.

Abandoned luggage, rubbish and personal possessions litter the near-empty boarding gates as an alarm sounds around the terminal.

The clip was recorded at Fort Lauderdale Airport on Friday night, hours after the 1pm massacre which left five people dead.
