Warsaw firefighters say that a Ryanair plane carrying 160 passengers from Oslo, Norway, to Warsaw's Modlin Airport made an emergency landing there because there was a suspicion of explosives on the aircraft.

Spokesman Pawel Pomorski said Thursday that 13 units of firefighters assisted the safe landing. No one was hurt.

He added that explosives experts are checking the plane. The passeners have been safely evacuated.

Modlin is a small, auxiliary airport in Warsaw and is only used by Ryanair.
