A bomb scare forced the evacuation of the international arrivals terminal and a control tower at New York's JFK airport today.
Mr Alan Hicks, a spokesman for the Port Authority of New York and New Jersey, said the bomb threat was under investigation but backup systems were deployed and there was no disruption to air services.
Security at JFK and all other US airports has been substantially tightened since the September 11th attacks against New York's World Trade Center and the Pentagon near Washington.
