People in part of Bradford have been urged to keep their windows and doors closed as fire crews continue to tackle a large fire at a nearby scrap yard.
Fire crews were first called to the blaze on Nelson Street, just outside the city centre, on Wednesday evening and remained at the scene on Thursday.
A West Yorkshire Fire and Rescue Service spokesperson said seven pump appliances and one aerial appliance had been sent to a scrap yard building fire.
Crews were "requesting that people avoid the area if possible and those that live nearby close all their windows and doors to stop smoke entering their property", the spokesperson said.
The fire investigation team had been assessing the cause of the blaze and found that it had started in an adjacent business where waste was being burned, they added.
"Unfortunately, this got out of control, spreading to surrounding combustible materials, then to the adjacent units," the fire service spokesperson said.
