Flames and smoke poured from the side of a major power station where a fire broke out today.
The emergency services were alerted just before 2pm to the incident at the coal-fired Ferrybridge C Power Station.
West Yorkshire Fire and Rescue Service said 15 crews were tackling the blaze at the landmark power station beside the M62 and A1.

The fire service said no-one was injured in the blaze which has affected the third floor of a four-storey building.
"A number of members of the public have called our control room due to the plumes of smoke which can be seen in the surrounding area," a fire spokesman said.
The site beside the River Aire is operated by the energy giant SSE, and it has run three power stations since 1924. The current one has operated since 1966.
