THIS is the terrifying moment a petrol station explodes in a huge fireball in Rome leaving at least 21 people injured.

Glass was shattered and three people suffered severe burns after the shocking blast in an eastern neighbourhood in Rome.

A huge bang was heard across the capital, with pictures showing billowing clouds of black smoke filling the air.

While flames are seen spreading over the gas station and parked cars.

Shocking footage shows the collapsed building charred from the fire with rubble and glass strewn across the ground.

Emergency services – including seven ambulances, fire engines, and police forces – rushed to the scene at around 8am today to reports of the explosion.

At least 21 residents were injured, including a firefighter, eight police officers and a paramedic.

Firefighters are still tackling the flames and have secured the entire area.

Ares 118, the local ambulance service, rushed five people to the hospital who were treated for serious burns.

Nearby buildings have also reportedly been damaged by the explosion.

Local metro station C and the town sports centre have been closed, while residents in two buildings and attendees at a summer have been evacuated.

It is believed the fireball was caused by a pump that became detached from a petrol tank, although this is yet to be confirmed.

Italian interior minister, Matteo Piantedosi, said: “I am in constant contact with the police chief and the head of the fire department to closely follow the developments related to the explosion that occurred this morning in Rome.

“I am monitoring with particular attention the conditions of the injured, especially those of the police officers and firefighters who intervened promptly to provide first aid.

“Their readiness, courage and sense of duty demonstrated in dealing with the emergency represent an extraordinary example of dedication to public service, which deserves respect and gratitude from everyone.

“The necessary checks are now underway for the remediation of the area.”
