French authorities on July 27 ordered the closure of a mosque in the Paris region for six months, citing sermons and social media posts by its imams that officials say glorified terrorism, legitimized jihad, and incited violence, hatred, and discrimination.
The closure occurred in the context of growing political debates around the challenges posed by the expansion of Islam in the country.
The order targeted the “Chanteloup” mosque in Aulnay-sous-Bois, a suburb northeast of the capital in the Seine-Saint-Denis department. It was announced by the local prefecture, the regional arm of the French state administration.
The closure was ordered under a provision enacted in October 2017 that allows prefects to shut down places of worship where preaching is found to “incite violence or hatred, promote terrorism, or provoke acts of terrorism.”
A communique by the local prefect claimed that both the mosque’s regular imams and the guest speakers it hosted spread a “radical Islamist ideology” that “echoes the rhetoric of terrorist organizations, legitimizes jihad, and glorifies death as a martyr.” The administration added that the closure was warranted given the gravity and repetition of statements it judged “capable of inciting terrorist acts.”
The French news agency AFP reported that a video circulating on the social platform X earlier in the year showed an imam who had lectured at least once at the mosque urged Muslims to strike their children aged 11 and older if they failed to pray.
The mosque’s management has contested the order. Its attorney, Rafik Chekkat, announced on social media that the association had filed an emergency appeal with the Montreuil administrative court, arguing the case rested on insufficient, imprecise, and unsubstantiated evidence involving faulty interpretations of Quranic verses.
“The prefect of Seine-Saint-Denis faults an imam for having cited the Surah Al-Baqara at the Chanteloup mosque in Aulnay-sous-Bois, in order to justify its administrative closure,” Chekkat said in a tweet. “If the order is upheld by the courts, the Quran itself becomes grounds for closure.”
He said the mosque had already removed the two imams responsible for what he described as roughly 90% of the complaints against it and that mosque leaders had asked to meet with the prefect beforehand but were refused.
Regional outlet Ici Paris Île-de-France reported the association is also contesting a freeze on its bank accounts and a separate move to dissolve the managing association itself.
A hearing before the Montreuil court was held on Aug. 4; the mosque remained open pending the ruling that should be made public in the coming days.
This is the second time the mosque has faced a shutdown. In 2019, the prefecture ordered its closure after an inspection found the premises did not meet public safety requirements.
Another mosque in the department, in Pantin, closed for six months in 2020 for publicly criticizing history teacher Samuel Paty, who was beheaded that year after showing pupils caricatures of Mohammed, the central figure of the Islamic faith.
Since 2017, the French Senate has ordered seven houses of worship closed under the same provision in its first two years alone, following 19 mosque and prayer-hall closures carried out under France’s 2015–2017 state of emergency after the Paris terrorist attacks in 2015. A further wave followed France’s 2021 law against Islamist “separatism.”
The closure lands amid an ongoing, and polarizing, public conversation in France about the growth of Islam. Government figures put the number of Muslim places of worship nationwide — mosques and smaller prayer rooms combined — at roughly 2,600 in 2024, up from about eight mosques in 1975.
Estimates of France’s Muslim population vary by methodology; INSEE-linked survey data suggest Muslims make up roughly 10% of the metropolitan population, or 6 to 7 million people. A widely covered November 2025 survey by the polling institute IFOP put the adult Muslim share at 7% in 2025, up from 0.5% in 1985.
The closure of the Chanteloup mosque came just one day after the 10th anniversary of the murder of 85-year-old parish priest Jacques Hamel by two Islamic State-inspired attackers inside his own church during Mass on July 26, 2016.
It was the first time in France a terrorist attack had targeted worshippers during a religious service. The local Diocese of Rouen and the town of Saint-Étienne-du-Rouvray — where Hamel was slaughtered — held two days of commemorations July 25 and 26.
A Mass was celebrated by the president of the French bishops’ conference, Cardinal Jean-Marc Aveline, with the homily delivered by Rouen’s Archbishop Dominique Lebrun, built explicitly around interreligious dialogue rather than security concerns.
Saturday’s program featured a roundtable titled “Muslims and Catholics: Educating Young People to Encounter One Another.” Organizers highlighted the public friendship between Roseline Hamel, the slain priest’s sister, and Nassera Kermiche, the mother of one of his killers, as the defining symbol of the decade since the attack.
