Further to Ian's eye-witness report of the blast in Wapping yesterday:

Firecrews are still damping down at the site of a blaze which caused a hugh pall of smoke over east London.

Around 80 firefighters tackled the blaze at a builders' yard in Raine Street, Wapping, which is believed to have started in a skip.

It is thought it began to spread when 50 tonnes of roofing material, which had only been delivered the day before, caught alight.

That spread to propane gas cylinders, which exploded, raining debris on to a nearby elderly peoples' home.
