Residents warned over exploding gas cylinder fears

Firefighters have warned residents in London that an ongoing blaze could spark the explosion of a gas cylinder.

Police are evacuating properties in the immediate area of the blaze at a air conditioning workshop and offices in Harrow, north-west London.

A acetylene cylinder is believed to be involved and a 75 metre hazard zone has been put in place as a precaution as up to 60 firefighters attempt to bring the fire under control.

Chris Andoh shared a video of firefighters dealing with the fire.

London Fire Brigade advised people living nearby to keep their doors and windows closed.
