A huge fireball sent 50 foot clouds of smoke billowing into the sky as a lorry carrying chemicals caught fire perilously close to a petrol station.
Footage showed the moment a street in St Ives, Cambridgeshire, was lit up by the fire and people ran to safety.
The truck was left completely incinerated by the blaze but amazingly no one was injured.
Eye-witnesses described the intense heat and horrible smell of burning chemicals.
Others said they could hear noise from the explosion up to seven miles away.
Footage shared on social media showed people getting very close to the fire ball to have a closer look.
The blaze completely filled the road and sent vast plumes of smoke into the air.
More than 20 firefighters managed to extinguish the fire but a specialist clean-up operation was still on-going late last night and the road needs to be resurfaced because of the damage.
A spokesperson for Cambridge Fire and Rescue said: ‘More than 20 firefighters, including crews from Huntingdon, Papworth, Gamlingay, Cambridge and Ramsey, including the water carrier, attended the incident.
‘The crews arrived to find a well-developed fire involving a lorry. Wearing breathing apparatus they extinguished the fire using hose reels.
‘There were no casualties requiring treatment for any injury.
‘The crews remain at the scene damping down the area and making sure it is safe.’
