Authorities say a gunman shot two officers, killing one and injuring another, before being killed himself in an attack on a popular shopping district Paris.

Paris Police and Soldiers have sealed off the area around the famed boulevard, ordering tourists back into their hotels and blocking people from approaching the scene.

The French Interior Ministry says the shooting attack deliberately targeted police officers guarding the area.

Security forces are more widespread in Paris since deadly Islamic extremist attacks in recent years, and France remains under a state of emergency.
