A woman in her 60s has been killed and three others are fighting for their lives after a horror smash on the A470 in North Wales.
Emergency services rushed to the two-vehicle collision between Dolwyddelan and Betws-y-Coed at approximately 4.45pm on Thursday.
The crash prompted a huge response from emergency crews, including two Welsh Air Ambulances and three land vehicles, reported NorthWalesLive.
A spokesperson for the Welsh Ambulance Service (WAS) confirmed they received a call at 4.47pm and multiple crews had been dispatched.
North Wales Police closed the road for several hours while fire and ambulance crews worked at the scene.
Welsh Air Ambulances G-WROL and G-WOBR landed at the scene at 5.12pm and 5.29pm, respectively. Both aircraft left the scene by 7.30pm and travelled eastbound, landing at the Royal Stoke University Hospital which is home to a Major Trauma Centre for serious injuries.
In a statement released on Thursday night, police said the crash involved a cream-coloured Renault Captur and a beige-coloured Daimler vintage car.
A female passenger in her 60s, who was in the Daimler, was pronounced dead at the scene.
Police said the male driver of the Daimler and the front seat passenger from the Renault were airlifted to hospital in Stoke by the Air Ambulance. The driver of the Renault was taken to hospital in Stoke by land ambulance.
Sergeant Jason Diamond of the Roads Policing Unit is appealing for witnesses.
He said: "Sadly, this is now being investigated as a fatal road traffic collision and our thoughts remain with everyone involved.
“We believe that the Renault was travelling towards the Betws-y-Coed area with the Daimler travelling in the opposite direction towards Dolwyddelan and I am urging anybody who may have seen either vehicle being driven prior to the collision, or anybody who may have been travelling along the A470 and who may have dash cam footage, to contact us immediately."
Anybody with information that could assist with the investigation is urged to contact officers at the Roads Policing Unit via the live web chat or by calling 101, quoting incident number B071845.
