A fire on board a double-decker bus caused long delays on the M22 motorway in County Antrim on Monday.

The blaze on the Ulsterbus service from Belfast to Londonderry started just before 17:30 BST, about 40 minutes after it began its journey.

A Translink spokeswoman said the driver got all the passengers out of the vehicle and called firefighters.

The bus was extensively damaged by flames and Translink said an investigation has begun.

Watch the fire on the bus here.

The Northern Ireland Fire and Rescue Service (NIFRS) said the bus was well alight when firefighters reached the scene.

They added that the bus driver sustained a cut to her hand while trying to remove the fire extinguisher.

Three fire appliances attended the incident, which caused long tailbacks on the M22 near Randalstown.

The fire has now been extinguished.
