VIDEO: The Primark fire in Belfast as it worsens on the roof

The film shows the blaze worsening, as fire engines continue to arrive and crowds gather.

Then there is footage from Castle Street, where small explosion sounds can be heard as firefighters on cranes tackle the conflagration.

Finally film taken from City Hall, looking back at the smoke rising, at 12.30pm. At that stage the fire seemed to be lessening and under control.

But then it got worse again through lower parts of the building.
