Two police officers have been killed in a shooting incident in central Paris, French police say. The suspected attacker was also killed, according to police. One officer died at the scene, the other died of his wounds shortly afterwards.

The shooting took place on the central boulevard of Champs Elysees. The French Interior Ministry confirmed in a Twitter post that the attacker targeted a police bus parked on the boulevard. The gunman who killed the police officer was already known to law enforcement services, police confirmed without revealing the identity of the attacker.

A large number of police officers have been deployed to the scene and the area has been cleared. A police source said the assault was “very probably” a “terrorist act,” with two attackers apparently involved. It has also been reported that shots were fired at another location near the Champs Elysees boulevard.
