New York: Hundreds of passengers and staff were evacuated from a terminal at New York City`s Kennedy Airport after a metal detector malfunctioned at a security checkpoint.
The Transportation Security Administration says it closed Kennedy`s Terminal 7 for about two hours on Saturday morning after discovering the equipment problem and realising that people had been let through without being properly screened.
Procedures call for the entire terminal to be emptied and passengers re-checked whenever that happens.
Some travellers have posted photographs on Twitter showing the lobby jammed with people waiting to get back in.
The terminal is used by British Airways, United, and other airlines.
The Port Authority of New York and New Jersey says the screening checkpoints were reopened to passengers by 11:45 am.
