At least two people were killed and dozens more injured on Monday after two lorries collided on the motorway near Bologna airport in northern Italy, causing a major explosion.
Footage from the scene shows a huge ball of fire and plumes of black smoke soaring into the sky following the collision.
At least two people were killed and 67 injured in the incident, according to police.
More than a dozen of the people injured were suffering from serious burns.
Police said they had closed off the road where the crash took place as well as the surrounding area in Borgo Panigale, on the outskirts of Bologna.
"It is advisable not to approach the area," they wrote on Twitter alongside a picture of damage caused by the accident.

Part of the bridge collapsed in the resulting explosion and fire spread to a car park below the bridge, where several other vehicles caught fire and exploded.
