Assistant Chief Fire Officer Dave Walton said that firefighters had remarked that the crash was "the worst they had seen in a number of years".
"The crews that arrived described to me a very difficult scene, some of them saying it was the worst they'd seen in a number of years, and some very experienced fire officers have been attending this scene.
"However, they very quickly got to work and brought in a range of equipment including cutting and lifting equipment to effect as quick a rescue as we could of those casualties who were still in the vehicle."
