Twelve double-decker buses have been damaged in a fire which sent plumes of smoke across London.
About 50 firefighters tackled the blaze at the Westbourne Park Bus Garage in west London, on Sunday, which is now under control.
Police said initially three vehicles were on fire when they were called, but there were subsequent explosions.
The Great Western Road, the A40 and Westbourne Park Tube station have all reopened after being shut for hours.
A spokesman for bus company First confirmed the fire was estimated to have caused hundreds of thousands of pounds of damage.
He said: "It looks like seven buses have been burned out and three to four are smoke damaged."
The spokesman added that it was a "complete mystery" as to how the blaze had begun, but confirmed there had been no casualties.
He said the incident had happened in an outside area, where the buses had been parked overnight.
Services would not be affected, the spokesman said.
