An airport was temporarily closed today amid fears there were explosives on board a Ryanair flight.
The airline put the alarm down to an "anonymous call", which was believed to be a hoax, after investigations turned up no sign of a bomb.
Officials shut down Modlin airport, near Warsaw, after the alert was received about a plane due to fly to Oslo.
Photos showed the aircraft surrounded by fire engines, police and bomb disposal experts on the runway and Modlin airport's official Twitter account posted a picture of travellers in the car park after they were evacuated from the passenger terminal.
A spokesperson for Ryanair said: “Warsaw Modlin Airport received an anonymous hoax call this morning that there was an explosive device on a Ryanair aircraft due to take off from Warsaw Modlin to Oslo at 8.40am local time (7.40am BST).

"The airport security authorities ordered an immediate inspection of the aircraft, which hadn't yet boarded, and closed the airport to inbound arrivals as a security precaution.
"The security sweep confirmed this was a hoax and the aircraft has returned to service, while the airport has since reopened.
"Ryanair sincerely apologises to the customers of the outbound Oslo flight for any inconvenience caused."
Previous reports by Reuters and Polish media mistakenly claimed the plane had made an emergency landing.
Polish police said they have detained a 48-year-old man man believed to be responsible for the call.
