The mosque in a densely-populated suburb northeast of Paris had published a video on its Facebook page days before Friday’s gruesome murder Education Minister Jean-Michel Blanquer said Tuesday that Paty would be posthumously bestowed France’s highest order of merit, the Legion of Honour PARIS: French authorities said Tuesday they would close a Paris mosque in a clampdown on radicalism that has yielded over a dozen arrests following the beheading of a teacher who had shown his pupils cartoons of the Prophet Muhammad. The mosque in a densely-populated suburb northeast of Paris had published a video on its Facebook page days before Friday’s gruesome murder, railing against teacher Samuel Paty’s choice of material for a class discussion on freedom of expression, said a source close to the investigation. The interior ministry said the mosque in Pantin, which has some 1,500 worshippers, would be shut on Wednesday night for six months. Interior Minister Gerald Darmanin has vowed there would be “not a minute’s respite for enemies of the Republic.” The order came after police on Monday launched a series of raids targeting extremist networks, mainly in the Paris region. Paty, 47, was attacked on his way home from the junior high school where he taught in Conflans-Sainte-Honorine, 40 kilometers (25 miles) northwest of the capital. A photo of the teacher and a message confessing to his murder was found on the mobile phone of his killer, 18-year-old Chechen Abdullakh Anzorov, who also posted images of the decapitated body on Twitter. Anzorov was shot dead by police. Education Minister Jean-Michel Blanquer said Tuesday that Paty would be posthumously bestowed France’s highest order of merit, the Legion of Honour, for having been “martyred” because of his profession. The murder was preceded by a fierce online campaign against Paty and the school, led by the father of a schoolgirl. The school said Paty had given Muslim pupils the choice to leave the classroom. The father who posted the video shared by the Pantin mosque is among 15 people arrested after the killing, along with a known radical and four members of Anzorov’s family. Darmanin accused the father and the radical of having issued a “fatwa” against the teacher. On Tuesday, the head of the Pantin mosque, M’hammed Henniche, said he had shared the video not to “validate” the complaint about the cartoons, but out of fear that Muslim children were singled out in class. Four pupils suspected of accepting payment for pointing Paty out to his killer were also taken into custody Monday. Junior interior minister Marlene Schiappa was to meet the French bosses of social media networks Tuesday to discuss bolstering the “fight against cyber-extremism.” Paty’s killing has drawn parallels with the 2015 massacre at French satirical magazine Charlie Hebdo, where 12 people, including cartoonists, were gunned down for publishing cartoons of the Prophet Muhammad. Tens of thousands of people took part in rallies countrywide on Sunday to honor Paty and defend freedom of expression, while Muslim leaders gathered at his school Monday to offer condolences and distance their religion from the atrocity. French President Emmanuel Macron threatened that “fear is about to change sides” in the new anti-extremist campaign. Paty’s beheading was the second knife attack since a trial started last month over the Charlie Hebdo killings. In the September attack, two people were wounded outside the publication’s former offices. A silent march is planned for Conflans-Sainte-Honorine on Tuesday evening in homage to Paty, while parliament will observe a minute of silence in the afternoon. Macron will attend an official homage with Paty’s family Wednesday at the Sorbonne university. Blanquer added that schools countrywide will observe a minute’s silence for Paty when pupils return after the autumn break, and a special lesson on the recent events will be taught in all classes. Justice Minister Eric Dupond-Moretti on Tuesday denied there had been any failure on the part of intelligence services. “This is an insidious war,” he told France Inter. “There is organized terrorism that is monitored by our services, and then there is a young man of 18 who was not on the radar of the intelligence services and who committed this abominable act.” Meanwhile, Paris prosecutors said they had opened an investigation into a French neo-Nazi website hosted abroad that republished the photo of Paty’s decapitated corpse posted to Twitter by the killer.
