Two people have died and hundreds have been arrested across France after Paris Saint-Germain (PSG) fans celebrated the club's victory in the Champions League final, according to the French interior ministry.
In the south-west town of Dax, a 17-year-old boy died after being stabbed in the chest late on Saturday evening, local media reported.
A 23-year-old man who was riding a scooter in central Paris was also killed after being hit by a vehicle, the prosecutor's office said.
Flares and fireworks were set off, bus shelters smashed and cars torched amid wild celebrations as PSG won the biggest prize in European club football for the first time in their history.
The French interior ministry told news outlets that 192 people were injured and 559 people arrested, including 491 in Paris.
Dax Mayor Julien Dubois said his "thoughts are with the young victim, his family and friends".
"We are floored by all the drama tonight," he wrote on social media. "It is advisable to quickly shed light on these facts in order to severely punish the perpetrator."
The Paris Prosecutor's Office told the BBC that two police officers were injured by objects thrown at Place des Ternes; while "several shops were looted" in the same area.
About 30 people were arrested and taken into custody near a Foot Locker on the Champs-Elysées that was robbed, the office said.
While clashes broke out near the city's Champs-Élysées avenue and PSG's Parc des Princes stadium, the majority of fans celebrated PSG's 5-0 win over Inter Milan peacefully, with many singing and dancing in the streets or blaring their car horns.
The Eiffel Tower was illuminated with PSG's blue and red colours.
French President Emmanuel Macron, a keen supporter of rivals Olympique de Marseille, posted on X: "A glorious day for PSG! Bravo, we are all proud. Paris, the capital of Europe this evening."
Approximately 5,400 police were deployed across Paris in anticipation of the raucous celebrations.
At least 300 people detained were suspected of possessing fireworks and causing disorder, Paris police said.
"Troublemakers on the Champs-Elysees were looking to create incidents and repeatedly came into contact with police by throwing large fireworks and other objects," police said in a statement.
