A large fire has broken out at a waste facility close to Wembley Stadium in north-west London, shutting Tube and train lines in the area.
The London Fire Brigade (LFB) said 125 firefighters were tackling the blaze at an industrial estate on Hannah Close in Neasden, with the smoke plumes visible from miles away in central London.
The LFB was alerted just after 11:30 BST and has deployed 20 fire engines to the scene. Residents have been warned to keep their windows and doors shut because of the huge amount of smoke.
Transport for London (TfL) said the entire Metropolitan line has been suspended as a result, while the Jubilee line has been part shut between Willesden Green and Wembley Park.
Rail services to and from London Marylebone are also being delayed or cancelled due to train lines being blocked, National Rail said.
A TfL spokesperson said: “We’re continuing to liaise with LFB to make sure we understand what we can operate safely for both our customers and staff.”
The industrial unit on fire is approximately 100m by 150m (161,400 sq ft), the LFB said.
The brigade added it had received more than 70 calls reporting the blaze and the cause is unknown.
BBC News understands that an Amazon delivery facility based in the industrial estate has not been directly impacted by the fire, but staff have been evacuated as precaution.
