The Islamic State (ISIS) terrorist group has claimed responsibility for Thursday's shooting in Paris on the Champs-Élysées.

The attack left one police officer dead and two other officers severely injured.

According to ISIS news agency Amaq, the shooter was Abu Yusuf al-Beljiki, USA Today reports. The American-based organization SITE Intel Group, who monitors terror activities and communications on the Internet, found the ISIS claim for al-Beljiki's actions.

French authorities say the targeting of police was intentional in this terrorist attack.

Since the shooting, there was speculation as to whether the shooting was a random criminal incident in a major city or whether terrorism played a role. Paris and the entirety of France has been attacked before in ISIS-claimed incidents, including a truck attack in Nice and bombings and shootings in Paris.

Thursday's shooting comes as France is engaged in a presidential election. Four main candidates are in close contention, with Marine Le Pen drawing the most attention. Le Pen has spoken out against immigration and recently said that she would suspend all immigration into the country.
