Five people have been left injured after a block of flats reportedly exploded this evening.
Fire crews from four stations, police and paramedics raced to the scene of a large building explosion in Skelmersdale shortly before 6pm on Tuesday.
A spokesperson for Lancashire Fire said they were aware of a 'number of casualties' being treated by paramedics.
A number of residents in the area are also being evacuated from the area.
Residents reported on social media hearing 'the ground shake' when the explosion happened, LancsLive reports.
The condition of those injured is now known at this time. The cause of the suspected gas explosion is also unclear.
