Firefighters have been tackling two major blazes in the West Midlands.
More than 60 firefighters were called to a suspected arson attack on a derelict warehouse in Tipton on Saturday night.
A large number of bales of recycling materials were "almost certainly" set alight deliberately, a fire spokesman said.
Crews were also called to four terraced houses on fire in Tile Cross. Six people were safely evacuated.
Ten fire engines were called to the scene in Saint Giles Road at about 06:00 BST.
The fire started in the rear of the end terrace but it quickly spread via the roofs.
No-one suffered any injuries but there was thick smoke coming from the properties.
The spokesman said: "The smoke was so bad at one point, you could not see the crews there."
Investigations have started into both fires, he added.
