More than 100 firefighters are battling a huge blaze that has engulfed a tower block in flames and smoke in west London.

Twenty crews from across the capital were called to the scene at Bush Court, Shepherd's Bush Green, after more than 40 witnesses called emergency services in the busy area today.

Hundreds of people were evacuated from the huge block as firefighters desperately fought to get the blaze under control after it broke out at around 3.45pm.

Witness Helena Noifield told BBC Radio London: 'Everyone's standing around not knowing where to go.

'It's all pretty horrible really. There's ash everywhere, smoke everywhere... it's like something out of a horror film. It's ghastly.'

The London Fire Brigade (LFB) said there were no initial reports of anyone trapped inside but officers are still at the scene investigating the blaze.

Crowds of people were spotted gathered outside a large area cordoned off by tape, amid dozens of fire engines and police vehicles gathered at the scene in rush hour.

The LFB warned people to expect road closures in the busy road, which could cause massive tail backs as vehicles try to get through the normally congested area at what is the busiest time of the day.

Huge plumes of grey smoke could be seen emerging from the block, and videos posted on social media showed flames billowing out of a seventh floor window.

'The cause of the fire is not known at this stage,' an LFB spokesman said.

The fire was brought under control after around two hours but firefighters remain at the scene trying to make it safe.
