A dozen houses in west Belfast have been evacuated because of a large blaze.
The fire service said significant damage has been caused to three houses in Sunnyhill Park and the roofs of two have collapsed.
No-one has been injured.
Sixty firefighters and eight appliances attended.
Northern Ireland Fire and Rescue Service area commander Kevin O'Neill said firefighters were called to a shed on fire but it spread to an oil tank.
"The oil from that oil tank flowed across the back of several properties, setting fire to other oil tanks, causing partial roof collapse on two properties."
The area was left a scene of devastation, with houses blackened by smoke and gaping holes in roofs.
