Greenwich chemical plant hit by fire
A large fire broke out at a chemical processing plant in south-east London, sending smoke billowing over the city.
A dozen fire crews fought the flames, which were spotted at 03:30 BST, at the factory in Peterboat Close, Greenwich, near the Blackwall Tunnel.
About half of the factory warehouse was alight when the fire was at its peak.
The flames were extinguished by about 06:50, London Fire Brigade said. One lane was closed on the Blackwall Tunnel Southern Approach, leading to delays.
Rimvydas Ivoskis, from Greenwich, said: "The air siren woke me up and upon seeing huge smoke coming from behind neighbours' houses I went out to take photos."
A caller to BBC London said there was thick smoke on the Old Kent Road, a couple of miles to the west of the fire.
He said: "You can't see your hand in front of your face.
"It is like a smelly fog."
