PARIS.- Two people died in a shooting Thursday night on the Champs-Elysees, this capital's iconic main avenue, French authorities said.
One policeman was killed and two other officers were badly wounded, while the assailant was fatally shot by security forces, the interior ministry said on its official Twitter account.
The attacker opened fire on a stationary police vehicle, the ministry said.
Officials declined to characterize the incident, which comes just three days before French voters head to the polls for the first round of the presidential election.
Paris police ordered the immediate evacuation of the Champs-Elysees and suspension of service at nearby metro stations.
The government urged people to beware of disinformation and to refrain from spreading rumors.
Amid accounts of additional shots being fired, the interior ministry said that there were no other ongoing security operations on the Champs-Elysees.
France's prime minister, Bernard Cazeneuve, said on Twitter that his thoughts were with the family of the slain police officer.
"Solidarity with his wounded colleagues and their loved ones," the prime minister tweeted.
Islamic State claim deadly Paris shooting
The attack in the heart of the capital of France has now been claimed by Islamic extremists.
Isis have claimed the attack via the Amaq news agency.
Police sources in Paris, as well as French president Francois Hollande, have confirmed they suspect terrorism.
