A petition urging the French government to ban a television news channel known for its hard line on immigration and crime has accrued more than 500,000 signatures amid accusations that its sensationalist coverage contributed to the racist killing of a Black man.

The petition to shut down CNews was launched in June, but support spiked after a Frenchman of Congolese origin was killed in a racially motivated attack in the Paris suburbs on October 23.

A 39-year-old man has been charged with murder and attempted murder over the incident in the commuter towns of Trappes and La Verriere west of Paris in which he said he was "targeting individuals who appeared to be Muslim, African, or North African," a prosecutor has said.

France: What is CNews?
French media have reported that the suspect was an avid consumer of CNews, which has been described as a French version of Fox News and criticized for giving too much airtime to anti-immigrant rhetoric.

The petition to "remove CNews from French broadcasting" argues that the channel, which is owned ​by conservative French billionaire Vincent Bollore, is not an ​information channel but a"propaganda machine."

Critics have claimed that CNews' broadcasting increasingly mimics lines taken by ​Le Pen's far-right National Rally (RN), which is leading in polls ahead of next year's presidential election.

Le Pen has promised to privatize public broadcasting in France, a policy from which CNews would stand to benefit.

At a rally in the northern Paris suburb of Aubervilliers last week, protesters held up posters reading slogans such as "CNews kills."

During nationwide cost-of-living protests on October 17, protesters threw projectiles and broke windows at the channel's Paris headquarters.

Meanwhile, two Green lawmakers have urged France's lower house of parliament to withdraw accreditation for CNews to protect "democracy" from "racist hatred."

Earlier this year, France expelled Russian news pundit Xenia Fedorova, who had been accused of peddling Kremlin propaganda on CNews.

CNews refuses to comment on 'political petition'
The channel has also been accused of broadcasting racist comments about Bally Bagayoko, a Frenchman of Malian descent who is the mayor of Paris' largest suburb, Saint-Denis, and who has gained prominence for his role in defending students in his constituency against police violence during recent protests.

CNews, which has previously denied allegations it promotes far-right views and racist tropes, saying it defends freedom of expression, told the French AFP news agency it would not comment on a "political petition."

At its launch in 2017, CNews had just a 1% market share but last year became France's most-watched free-to-air news channel.

Under National Assembly rules, a ⁠public ​debate can be organized in parliament ​if a petition attracts at least 500,000 signatures.

However, a parliamentary commission must ​ first review the petition and decide whether a debate can take place.
