Macron added that a pro-Hamas group active in France would be dissolved for being “directly implicated” in the murder of the teacher.
A man who beheaded a history teacher outside Paris last week had been in contact with a parent leading an online campaign against the teacher, the investigation into the killing revealed Tuesday.
The breakthrough in the case came as President Emmanuel Macron promised more pressure on Islamist extremism after days of clampdowns which have resulted in over a dozen arrests, a mosque ordered shut and a pro-Hamas group to be dissolved.
“Our fellow citizens expect actions,” Mr. Macron said during a visit to a Paris suburb. “These actions will be stepped up.”
Police sources said earlier that the 18-year-old killer had exchanged messages on WhatsApp with the man who wanted Samuel Paty fired after his daughter told him how the teacher had shown cartoons of the Prophet Mohammed in a lesson on free speech.
The parent — the father of a girl in Paty’s class — was behind an online campaign urging “mobilisation” against the teacher.
‘Not a minute’s respite’
The man, now in police custody, had placed his phone number on Facebook and exchanged messages with the killer — 18-year-old Chechen Abdullakh Anzorov — on WhatsApp in the days leading up to the murder, police sources told AFP.
Anzorov was shot dead by police soon after the killing.
Among other messages, the father had published a video railing against Paty’s choice of lesson material.
The mosque, now targeted for a six-month closure, shared this video on its own Facebook Page.
Mr. Macron added that a pro-Hamas group active in France would be dissolved for being “directly implicated” in the murder of the teacher.
The decision to shut down the “Cheikh Yassine Collective”, which supports the Palestinian cause and is named after the Hamas founder, will be taken at a Wednesday’s cabinet meeting, he said.
The group’s founder and Islamist radical, Abdelhakim Sefrioui, is currently being held by police for publishing a video on YouTube insulting Paty.
Prime Minister Jean Castex told MPs on Tuesday that the government was now targeting “all associations whose complicity with radical Islamism has been established”.
Paty, 47, was attacked Friday on his way home from the junior high school where he taught in Conflans-Sainte-Honorine, 40 kilometres (25 miles) northwest of Paris.
Police have arrested 16 people in connection with the killing, including and four members of Anzorov’s family.
Interior Minister Gerald Darmanin vowed there would be “not a minute’s respite for enemies of the Republic”.
Education Minister Jean-Michel Blanquer said Tuesday that Paty would be posthumously bestowed France’s highest order of merit, the Legion of Honour.
The school said Paty had given Muslim pupils the choice to leave the classroom before he showed the cartoons.
But the girl’s father was outraged by him displaying a caricature of the prophet naked, and sought Paty’s dismissal for disseminating “pornography”.
On Tuesday, the head of the Pantin mosque, M’hammed Henniche, said he had shared the father’s video out of fear that Muslim children were being singled out in class.
Five pupils suspected of accepting payment for pointing Paty out to his killer were among those in police custody.
‘The decapitated Republic’
Paty’s beheading was the second knife attack claimed in the name of avenging the Prophet since a trial started last month over the Charlie Hebdo killings in 2015 when 12 people, including cartoonists, were gunned down for publishing Mohammed cartoons.
After Paty’s murder, Mr. Macron threatened that “fear is about to change sides”.
Junior interior minister Marlene Schiappa assembled French bosses of social networks Tuesday to discuss bolstering the “fight against cyber-Islamism”.
Tens of thousands of people took part in rallies countrywide over the weekend to honour Paty and defend freedom of expression.
The French parliament observed a minute of silence for Paty on Tuesday, while thousands gathered for a silent march in the teacher’s honour in Conflans-Sainte-Honorine in the evening.
Mr. Macron will attend an official homage with Paty’s family Wednesday at the Sorbonne university.
Darmanin has called for vigilance at schools to be bolstered when pupils return after the autumn break.
The next edition of Charlie Hebdo, meanwhile, will feature the headline “The decapitated Republic” on its front page along with cartoons representing various professions, the weekly said Tuesday.
“These murderers want to decapitate democracy itself,” reads the editorial to be published Wednesday.
