Large fire at Wales industrial estate after explosion

Firefighters are still tackling a huge blaze at an industrial estate in south Wales and one person remains unaccounted for.

South Wales Fire and Rescue Service said it was still tackling the fire in Pontypridd in various parts.

Police said there were no reports of serious injuries but the MP for the area said there were "walking wounded".

Images on social media in the aftermath showed a building in flames and smoke at Treforest Industrial Estate.

At least one building was destroyed and a "major incident" was declared for several hours following the "massive explosion" at 19:00 GMT.

The fire service said a two-storey building was "at risk of collapse" and it had seven pumps at the scene, along with an incident command unit.

Roads in the area remain closed and an investigation is taking place into the cause.

The Welsh Ambulance Service said it "treated three patients at the scene before discharging them" on Wednesday evening.

South Wales Police said there no reports of serious injuries but "one person remains unaccounted for".

The force said on Wednesday: "Residents living nearby are advised to close all doors and windows while this incident is continuing.

"Businesses in the area are requested to implement their own business continuity plans to deal with the on-going road closures."

The fire is in a 60,000 sq ft (5,574 sq m) warehouse called Rizla House which houses 13 commercial units including a gym, a towel manufacturer, a food laboratory and a telecoms service company.

Cwm Taf Morgannwg health board had put all its emergency departments on high alert for several hours, standing down late on Wednesday.

It also asked people to "continue to make appropriate use of urgent care services to ensure those that most need our care can receive it in a timely way".

Alex Davies-Jones, MP for Pontypridd, said on Wednesday evening: "There have been a couple of walking wounded, but not more than that at the moment.

"We will know more in the morning."

She said police were advising concerned family members to visit Talbot Green Police Station.

One nearby business owner said her tattoo shop "just exploded".

Lucy Artiss, tattooist at Sixteen Circles, said she had "lost everything" but all of her colleagues made it out of the building unhurt.

"I feel numb, to be honest. Looks like I'll need to find a new shop."

Nearby Integer Telecom, a telecommunication provider, said in a Facebook post its building was destroyed in the explosion, adding: "All our staff are safe and unharmed and business will resume as normal."

The manager of a nearby Esso garage, Krishnaraj Nadarajah, said he contacted the fire service and shut off pumps at the station.

The 40-year-old described hearing a "massive explosion".

He said: "It felt like it was an earthquake or something. We went outside and there was a fire starting to build up, it was a huge fire and smoke."

"The noise was very loud, it was a big explosion. Some of the things fell down in the store, off the shelves."

Mr Nadarajah called it "very scary".

Petwise Reptiles on Severn Road said it was "unaffected so far".

"We have staff at the scene waiting to enter the store to check out all our pets as soon as it's safe to do so," it said on Facebook.

Phill Jones from Llantrisant said he was driving along the A473 with his eight-year-old son at about 19:15 when he saw "a really loud bang and a flash of light".

"My first reaction was 'Who is letting off fireworks on a Wednesday night?'

"There was a big fireball up in the sky. I swerved the car a little bit and my son got quite animated.

"The way it went up, it was almost as if something had exploded."

Dr Aeliya Zaidi said she was travelling home along the A4119 when traffic began "piling up" and she saw lots of fire engines and ambulances.

The 40-year-old said: "There was a huge, huge fire - it looked very, very dramatic like the ones you see in the movies.

"There were lots of people on the roads making videos and taking photos."

Dr Zaidi, who works at the University Hospital of Wales in Cardiff, added: "Being a doctor, I was just thinking if any human lives are involved.

"Any other thing can be managed but of course if there's anybody inside they're somebody's relative and their life is important."

The owner of nearby Green Rooms, Jonny Foxhall, said the music venue's front door was flung open.

"We could see a smoke cloud and an orange glow from above the treeline quickly followed by flames," the 36-year-old said.

"To feel the shockwave from the explosion is something I've never experienced before."

In an update at 01:30 on Thursday, police said the following roads remain closed:
