Several hurt as gang storms video set of French rapper Booba

Shots were fired and several people injured overnight as gangs armed with guns and baseball bats stormed the set of a music video by controversial French rapper Booba, a police source told AFP Wednesday.

The 42-year-old musician, who is one of France's biggest rap stars, has been locked in a high-profile feud with fellow rapper Kaaris which exploded into violence at a Paris airport last year, landing them both in jail for a month.

Around 15 people were involved in the overnight attack which took place around midnight (2200 GMT) in the northeastern Paris suburb of Aulnay-sous-Bois, the source said, confirming a report first published by Europe 1 radio.

One of the injured sustained a bullet wound to the thigh but his injuries were not thought to be life-threatening, said the source. Booba was not there at the time, he said.

The ambush reportedly took place at a disused warehouse where the music video was being made, with the attackers pulling up to the site in cars and firing four shots towards Booba's crew as they put away equipment.

They then began attacking the rest of the crew with iron bars and baseball bats, with the video's producer sustaining serious head injuries and another technician also badly hurt, BFMTV said.

It said the man who sustained a gunshot wound to the leg was Booba's 36-year-old marketing and sponsorship manager.

Police found four 9mm shell casings and two cartridges at the scene and have opened an inquiry, the channel said.

It was not immediately clear who was behind the attack but it led to speculation it was linked to the ongoing feud between the two rappers which has made headlines in France and beyond.

Their August 2018 brawl at Orly airport erupted as the men and their entourages were about to fly to Barcelona for a concert, prompting officials to temporarily shut down part of the terminal, delaying flights.

A month in solitary and heavy fines did little to cool their animosity, however, with the two pledging to settle their differences through a two-million-euro cage fight in Switzerland in November.

The pair had been drumming up expectations for the MMA fight in the Swiss city of Basel, goading each other relentlessly.

They chose Switzerland for their fight because the ultra-violent sport of MMA -- or mixed martial arts -- is banned in France.

The winner would have walked away with 1.5 million euros (USD 1.7 million), while the loser would get just half a million.

But last week, Swiss authorities cancelled the fight, saying they had been misled about the nature of the event, ahead of which the pair had exchanged very public threats.

Ivory Coast-born Kaaris, 39, had promised he would drink his rival's blood, to which Booba replied. "I will beat you to death, you son of a bitch."
