Security has been increased at New York-area airports after a gunman fatally shot multiple people and injured several others at Fort Lauderdale-Hollywood International Airport in Florida Friday afternoon.

Authorities say five people were killed and eight others injured, and that a lone shooter was in custody. They were investigating reports of additional incidents, though none was substantiated.

As a result, the Port Authority of New York and New Jersey announced that Port Authority police are stepping up patrols and deployment of officers with heavy tactical weapons at agency airports, including John F. Kennedy International, Newark Liberty International and LaGuardia.
