A Virgin Atlantic plane carrying 357 people from Britain to the United States made an emergency landing at Keflavik airport in Iceland this morning following a bomb threat.
The plane, flight VS 27, carrying 339 passengers and 18 crew, was evacuated and then examined.
Bomb disposal crews entered the aircraft,
a Boeing 747 en route from Gatwick, England, to Orlando, Florida, but found nothing suspicious.
The bomb threat is believed to have come about one-and-a-half hours before the emergency landing when a message was found written on a toilet mirror.
A member of the cabin crew found the message scrawled on the mirror during a routine check.
Although the plane may never have been in immediate danger, it made an emergency landing under standard security regulations.
The Virgin Atlantic Boeing 747 took off from London's Gatwick airport at midnight last night (NZT) bound for Orlando, Florida.
It landed safely at Keflavik airport, 50 km southwest of the capital Reykjavik, around six hours later.
Keflavik police said the threat was written on a toilet mirror in the plane in soap. It was discovered by the crew and taken very seriously, he added.
The message apparently contained the phrase 'all Americans must die' and other anti-American sentiment.
