A shocking video shows warring gangs in Paris shoot "mortar rockets" at each other in front of a school.
In the clip, recorded on Saturday from an apartment window, yobs from two rival factions face off at either end of the street and fire improvised mortar rockets at each other in the French capital city.
A man charges up the street as his firework mortar fires and he narrowly dodges being hit by return fire.
The incident took place on Rue Rampal in the city's 19th arrondissement, next to a primary school, and less than 24 hours after improvised firework mortars were shot into a park full of children.
Footage of that mortar fight was also shared online, notching up 10s of thousands of views and sparking a furious backlash against the violent and risky tactics.
A woman who witnessed the incident told BFM Paris "everyone was terrified because the fireworks were hitting them".
She added: "They went into the park and targeted mums and kids who were playing there after school."
Locals were shaken during the incident and the footage has been widely aired by French TV channels.
The employees of a pharmacy located a few hundred metres from the square told Le Figaro they had welcomed "several people coming to take refuge from the fireworks" during the carnage.
"It spread all over the street, everything was smoky," they said.
Police said nobody was hurt during the shocking incidents at the children's playground, on September 11, and the gang fight on September 12.
The Paris police prefecture said: "There was a fight. There were no injuries or arrests but the police station has opened an investigation."
Fireworks can cause serious damage if misused and rockets can cause burns, soft tissue injuries and even fractured bones.
Last year, a 12-year-old girl in Coventry suffered burns to her back after thugs threw a lit firework into a branch of Domino's Pizza as a "prank".
