Smoke was seen rising from a fire next to Munich Airport in Germany on Thursday morning August 25.

Shocked passengers leaving a plane that had just landed noticed the large grey cloud rising into the sky behind the control tower to the west of the airport.

One passenger is heard saying in the video 'it's a bit dark, that's not good'.

The filmer said the smoke 'looked like a large fire due West of Munich International'.

A Munich Airport spokesman said: 'A biogas plant outside the airport ground is on fire.'

Footage from residents showed that the fire had started in grounds outside the airport. Flights have reportedly not been affected by the blaze, which reportedly started at a biogas plant.

Fire fighters attended the inferno, which local media reported was accompanied by several explosions.
