Firefighters were this morning tackling a huge building blaze in Beck Street, Keighley.

A fork lift truck containing gas containers was seen inside, sparking fears there may be an explosion on one side of the three-storey building.

Firefighters from Keighley, Bingley, Haworth, Silsden and Bradford, were initially called to the scene at about 3.45am.

The number of engines was stepped up to ten just after 7am, a spokesman for Keighley fire station said.

Specialist officers and a fire investigator also attended.

Police closed off New South Street both ways between the Worth Way and Oakworth Road junctions.
