PARIS - French President Emmanuel Macron denounced what he called an "Islamist terrorist attack" against a history teacher decapitated in a Paris suburb Friday, urging the nation to stand united against extremism.
The teacher had discussed caricatures of Islam's Prophet Muhammad with his class, authorities said. The suspected attacker was shot to death by police after Friday's beheading.
The French anti-terrorism prosecutor opened an investigation concerning murder with a suspected terrorist motive, the prosecutor's office said.
Macron visited the school where the teacher worked in the town of Conflans-Saint-Honorine and met with staff after the slaying. An Associated Press reporter saw three ambulances arrive at the scene, and heavily armed police surrounding the area and police vans lining leafy nearby streets.
"One of our compatriots was murdered today because he taught ... the freedom of expression, the freedom to believe or not believe," Macron said.
He said the attack shouldn't divide France because that's what the extremists want. "We must stand all together as citizens," he said.
The gruesome killing of the teacher occurred in the town of Conflans-Sainte-Honorine while the suspect was killed by police in adjoining Eragny.
A police official said the suspect, armed with a knife and an airsoft gun - which fires plastic pellets - was shot dead about 600 meters (yards) from where the male teacher was killed after he failed to respond to orders to put down his arms, and acted in a threatening manner.
