A bomb scare has forced the evacuation of 165 passengers from an Italian airliner that was preparing to leave Rome's main airport for London.

Authorities later determined it was a false alarm.

The passengers and their luggage were ordered off the Alitalia flight Saturday, after officials received an anonymous phone call announcing there was a bomb on the plane.

Bomb squad experts and sniffer dogs found nothing suspicious, and passengers were allowed back on the plane.

The flight was expected to depart for London after a delay of more than four hours.
