Gunshots were fired Thursday night on the Champs-Elysées in Paris and one police officer was killed.

CNN affiliate BFMTV is reporting that two policemen were seriously injured.

The avenue has been closed and authorities are telling people to avoid the area. Video showed the normally busy area empty of residents and tourists but teeming with security officers at 9:30 p.m at night, local time.

This is a developing story - more to come.
