The satirical magazine Charlie Hebdo, whose offices underwent a mass murder attack five years ago, was among groups organizing a tribute gathering to Patty in Paris in the afternoon.
The 47-year-old teacher was murdered on Friday by an 18-year-old attacker outside a school in a Paris suburb. A Russian-born attacker of Chechen origin was shot dead by the police immediately after the attack.
Earlier this month, the teacher showed Prophet Mohammed’s own cartoons in a class on freedom of expression, angering many Muslim parents. Muslims believe that any portrayal of the Prophet is defamatory.
The government has portrayed the murder as an attack on the heart of French values.
Education Minister Jean-Michel Blenker and politicians from Spectrum were to attend the commemoration held in central Paris on Sunday. A national tribute will be held by President Emanuel Macron’s office on Wednesday.
Prime Minister Jean Castex said the government was working on better strategies to protect teachers from threats. Patty was the target of an angry campaign on social media before the attack.
“I want teachers to know that, after this reckless act, the whole nation is behind them,” Castex told the Journal du Dimanche in an interview.
“This tragedy affects each of us because, through this teacher, it is the Republic that was attacked.”
There was no description of the 11th person detained in connection with the murder.
Four close relatives of the attacker were taken into custody immediately after the attack. Five more people were later detained, including an acquaintance of Patli’s father at Pati’s school and pupil known for intelligence services, anti-terrorism prosecutor Jean-Francois Ricard said Saturday.
A 10th person was detained on Saturday.
Macron was asked to have a security meeting with the chief ministers later on Sunday.
On Saturday, hundreds of people, including pupils and their parents, teachers and local residents, came to the school to express their grief and solidarity, where Patty worked the College du Bois d’Olein in the suburb of Conflance-Sainte-Honorin .
