Thousands of people gathered across France on Sunday to support teachers and defend freedom of expression after the killing of Samuel Paty, who was killed by a suspected terrorist. Mr Paty had been threatened after giving a lesson two weeks ago in which he showed pupils cartoons of the Prophet Mohammed to illustrate the idea of free speech. Prime Minister Jean Castex attended the gathering on Place de La Republique in Paris along with Education Minister Jean-Michel Blanquer and politicians from across the spectrum, showing solidarity after a killing that has shocked the country. In Lyon, Marseille and Lille, large crowds also gathered quietly, pausing regularly to applaud, hold minutes of silence or sing the national anthem. "You don't scare us. We are not afraid. You will not divide us. We are France," Mr Castex tweeted later. It was the latest attack in a deadly cycle of extremist attacks in France, that included: <strong>September 25, 2020 - </strong>Two people are stabbed and wounded in Paris near the former offices of the <em>Charlie Hebdo</em> satirical magazine, where terrorists carried out a deadly attack in 2015. A man originally from Pakistan is arrested over the attack. <strong>October 3, 2019 -</strong> Mickael Harpon, 45, an IT specialist with security clearance to work in the Paris police headquarters, kills three police officers and a civilian employee before being shot dead by police. <strong>March 23, 2018 -</strong> A gunman kills three people in south-western France after holding up a car, firing on police and taking hostages in a supermarket, yelling "Allahu akbar".
