JetBlue flight makes emergency landing in Texas

A US domestic flight made an emergency landing after the captain began yelling about a bomb, passengers say.

The airline said a "medical situation" involving the flight captain prompted the landing in Amarillo, Texas, about three-and-a-half hours into the flight.

JetBlue flight 191 from New York to Las Vegas was carrying 135 passengers when a crew member had to be locked out of the cockpit and restrained.

Local police and the FBI are said to be investigating the incident.

Footage appears to show the scene inside the plane and the pilot being taken off the aircraft in Amarillo, Texas.
