French Prime Minister Elisabeth Borne said Friday that the government was considering "all options" to restore order, including declaring a state of emergency, after a third night of rioting over a police officer's killing of a youth.

Asked by reporters if a state of emergency was a possibility, as some right-wing opposition parties have demanded, Borne replied: "I won't tell you now, but we are looking at all options, with one priority: restoring order throughout the country."

The prime minister, who was visiting a police station in Evry-Courcouronnes south of Paris, is to attend a crisis security meeting chaired by President Emmanuel Macron in the afternoon.
