Incredible photos have emerged of part of central London engulfed in darkness after an underground inferno.
More than 2,000 people were evacuated from offices and flats in Kingsway, Holborn, when flames spewed from street drains today.
The alarm was raised after smoke was seen billowing from an inspection cover at around 12.30pm.
The fire is believed to have started among electric cables.
A large cordon was set up around Holborn while emergency services dealt with the incident.
That part of London has since plunged into darkness due to multiple power cuts – and people have been sharing their eerie pictures on social media.
At the time onlookers reported ‘struggling to breathe’ and ‘chaos’ in the area as those evacuated waited on the street and traffic began to pile up.
Nicola Foxfield, 29, said: ‘I was walking from Covent Garden towards Holborn and I could smell burning in the air.
‘As I got closer I could see fire engines everywhere then I could see loads of thick, brown smoke rising off the road.
‘It’s chaos and fire engines are coming from every direction and there are so many people around.’
There are no reports of injury.
Kingsway between the Aldwych and High Holborn remains sealed off tonight as firefighters ‘dampen down’ the underground fire.
Other roads has since re-opened.
London Fire Brigade Assistant Commissioner Peter Cowup said: ‘Crews worked closely with the various electricity companies involved to identify the source and extent of the fire which was underground.
‘As this was likely to be an electrical fire we had to ensure the power was off before we applied water to extinguish it.
‘We worked with our partners and implemented a well-rehearsed plan to prevent the fire from spreading and to protect surrounding properties.
‘The power has now been isolated and so the fire is contained. Crews are now able to access what remains of the fire and will be at the scene into the night damping down.’
