An assailant opened fire on a police officer on the southern edge of Paris early Thursday, killing her and injuring a nearby street sweeper before fleeing, officials and a witness said, report agencies.
France's Interior Minister cautioned against jumping to conclusions on the shooting a day after the deadly assault on a satirical newspaper that killed 12 people.
The attacker in the pre-dawn shooting on Thursday remained at large, said French Interior Minister Bernard Cazeneuve. It was not immediately clear whether the attack was linked to the assault on the newspaper Charlie Hebdo, in which two police officers were among the dead.
In the Thursday shooting, Mr. Cazeneuve said, the officer had stopped to investigate a traffic accident when the firing started. Paris police said the second victim was a street sweeper. The officer later died of her injuries, said Emmanuel Cravello of the Alliance police union.
"There was an officer in front of a white car and a man running away who shot," said Ahmed Sassi, who saw the shooting from his home nearby.
Mr. Sassi said the shooter wore dark clothes but no mask. "It didn't look like a big gun because he held it with one hand," Mr. Sassi said.
Mr. Cazeneuve left an emergency government meeting to travel to the scene of the latest shooting. France is on its highest level of alert after the deadly attacks at Charlie Hebdo's central Paris offices.
Muslim places of worship in two French towns were fired upon overnight, leaving no casualties, prosecutors said on Thursday.

An explosion at a kebab shop near a mosque in the eastern French town of Villefranche-sur-Saone on Thursday morning also left no casualties. Local prosecutors have described it as a "criminal act".
Meanwhile, two brothers suspected of having gunned down 12 people in the attack on satirical magazine Charlie Hebdo were spotted on Thursday morning and are armed, sources close to the manhunt said.
