Champs-Elysees shooting: 1 police officer killed, another injured in Paris attack
DEVELOPING: One police officer has been killed and another has been wounded in a shooting Thursday on the Champs-Elysees in Paris, a French police source tells Sky News.
The person who fired on police has been killed, the law enforcement source told Sky News.
Authorities warned people in the heart of the French capital to avoid the area after the shooting, France 24 reported.
Many police vehicles can be seen on the avenue that passes many of the city's most iconic landmarks.
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.
France has been in a state of emergency following a series of terrorist attacks, including the the November 2015 attacks, which targeted the Bataclan concert hall and Stade de France sports arena in Paris and the deadly truck attack in Nice.
The state of emergency has been extended by several parliamentary votes and remains in effect.
