PARIS — Paris police say a gunman has killed a police officer and wounded another before being killed himself in an attack on the Champs-Elysees shopping district.
Paris police spokeswoman Johanna Primevert told the Associated Press that the attacker targeted police guarding the area near the Franklin Roosevelt subway station Thursday night at the center of the avenue popular with tourists.
Reuters reports that the officer was killed in a car stopped at a red light as the gunman drove by.
Reuters also reports police said the incident was likely “a terrorist act.” The news agency says police believe two attackers were involved and one was killed.
Many police vehicles can be seen on the avenue that passes many of the city’s most iconic landmarks.
Twitter user Massimo Cavazzini posted this video of police cars rushing to the scene:
The attack came three days before the first round of balloting in France’s tense presidential election. Security is high preceding the vote after police said they arrested two men Tuesday in what they described as a thwarted terror attack.
A witness identified only as Ines told French television station BFM that she heard a shooting and saw a man’s body on the ground before police quickly evacuated the area where she works in a shop.
The incident recalled two recent attacks on soldiers providing security at prominent locations around Paris, one at the Louvre museum in February and one at Orly airport last month.
A French television station hosting a televised event with the 11 candidates running for president briefly interrupted its broadcast to report the shootings.
None of the candidates immediately commented.
Police tweeted that people should avoid the area.
This is a developing story.
