Six people have been hurt after a bus crashed into a railway bridge, tearing its roof off.
The bus had been travelling along a road in Camden, north London. It had been sent off its normal route because of a major fire in the area.
Police say other buses had been safely travelling under the bridge for 24 hours, by driving along the middle of the road.
An investigation into what caused the crash has been set up.
Buses had been diverted from their normal routes because of a fire at Camden Market, a famous tourist attraction.
The fire caused lots of damage to buildings around the market, and experts are investigating whether they are safe.
