France will pay tribute Wednesday to a history teacher beheaded in a quiet Paris suburb as President Emmanuel Macron promised to intensify a clampdown on Islamist extremism.

Police have carried out dozens of raids, while the government has ordered the six-month closure of a mosque and plans to dissolve a group that supports Palestinian militant group Hamas.

“Our fellow citizens expect actions,” Macron said during a visit to a Paris suburb on Tuesday. “These actions will be stepped up.”
