A police officer has been killed and another wounded in what police believe was probably a terror shooting incident in Paris.

Police sources say the officers were attacked on the Champs-Elysees and the person who fired on them has also been killed. At least two attackers are reported to be involved and authorities are warning people to avoid the area.  Many police vehicles can be seen on the famous avenue.

An eyewitness told Reuters a man got out of a car and began shooting “with a kalashnikov.” Police say the officer who was killed was in a car which had been stopped at a red light by the attacker. A witness identified only as Ines told French television station BFM that she heard a shooting, saw a man’s body on the ground and the area was quickly evacuated by police.
