Seven buses have been destroyed and four others badly damaged in a huge blaze at a depot in south-east London.
About 60 firefighters were called to the site in Farnborough Hill, Orpington, at about 03:30 GMT.
People living nearby said they were woken by “explosions”. No-one was injured in the fire.
London Fire Brigade (LFB) received about 40 calls and described the blaze as “very visible”. It took nearly three hours to get it under control.
About 30 other vehicles stored at the garage were moved to prevent the flames spreading further.
A local resident, who asked not to be named, told the BBC it had started as “a little fire” but had “ignited within five minutes and buses were exploding”.
“I’ve never seen anything like it,” he said.
Fire crews will remain in the area “for some time damping down the affected vehicles”, LFB said.
It has warned people to avoid the area due to the number of fire engines in attendance.
There was a limited bus service running in Orpington until about 10:45 because of the blaze, according to Transport for London.
