At least two French prison guards were shot dead and three others seriously injured today after heavily armed men ambushed a prison van to free an inmate, French police said, triggering a major manhunt.
The Gunmen attacked the prison van at a motorway toll in northern France, killing at least two prison officers and freeing a convict who had been jailed last week.
President Emmanuel Macron vowed that everything would be done to find those behind the attack and hundreds of members of the security forces were deployed for a manhunt to find the attackers and the inmate who were all still at large.
Two prison officers were killed in the attack and two others were receiving urgent medical care, Paris prosecutor Laure Beccuau said.
The wounded officers' lives were in danger, Justice Minister Eric Dupond-Moretti said.
The incident took place late this morning at a road toll in Incarville in the Eure region of northern France.
The inmate was being transported between his prison in the town of Evreux and court in the regional centre of Rouen in Normandy.
A police source said several individuals, who arrived in two vehicles, rammed the police van and then fled.
One of them was wounded, the police source said.
It was not immediately clear how many attackers there were in total.
"Everything is being done to find the perpetrators of this crime," Mr Macron wrote on X.
"We will be uncompromising," he added, describing the attack as a "shock".
French television channels broadcast footage of the attack taken by surveillance cameras at the toll, showing a vehicle colliding head on with the prison van.
In the video, the doors of the car are flung open and several gunmen dressed in black emerge. A firefight ensues and one individual appears to be guided away from the van by the gunmen.

'All means used'
Mr Dupond-Moretti immediately headed to a crisis cell at his justice ministry.
"These are people for whom life counts for nothing. They will be arrested, they will be judged and they will be punished according to the crime they committed," he said.
The prison officers who died, both men, were the first to be killed in the line of duty since 1992, he added.
One of them was married and had two children while the other "left a wife who is five months pregnant", he said.
The prison convoy had no police escort, according to a source close to the case.
The source said guards were not systematic and only used for high-security prisoners, which was not the case for the inmate who fled.
A unit of the GIGN elite police force has been despatched to try and apprehend the suspects.
Traffic was stopped on the A154 motorway where the incident took place.
Interior Minister Gerald Darmanin said on X he had ordered the activation of France's Epervier plan, an operation launched by the gendarmerie in such situations.
"All means are being used to find these criminals. On my instructions, several hundred police officers and gendarmes were mobilised," he said.
Prosecutor Beccuau named the inmate as Mohamed Amra, born in 1994, saying that last week he had been convicted of aggravated robbery and also charged in a case of abduction leading to death.
The case has been handed to prosecutors from France's office for the fight against organised crime, known by their acronym JUNALCO.
However a source close to the case said that Amra was suspected of involvement in drug trafficking and suspected of ordering gangland killings.
Another source said he is suspected of being at the head of a network.
