A video showing smoked-filled plane in the air is currently viral on social media.
In the video, some of the passengers appear calm, but you can hear the sound of people praying and chanting.
One of the clips has been taken from the Twitter account of a passenger who has also been tweeting details of what happened.
She says she was on a flight from the southern city of Port Harcourt to the commercial capital, of Lagos, when the cabin started filling with smoke and people started praying.
She then says that the plane landed safely in Lagos with the emergency services on hand to help.
It is not clear exactly what happened and there are no reports that anyone was hurt.
