Two attackers killed a priest with a blade and seriously wounded another hostage in a church in northern France today before being shot dead by French police.
There were no immediate details on the identity or motives of the two assailants but the investigation was handed to the anti-terrorist unit of the Paris prosecutor's office.
A police source said it appeared that the priest had had his throat slit.
"At one point, the two assailants came out of the church and that's when they were killed by the BRI elite force," Interior Ministry spokesman Pierre-Henry Brandet told France Info radio, referring to France's specialised police group.
Prime Minister Manuel Valls branded the attack "barbaric" and said it was a blow to all Catholics and the whole of France.
"We will stand together," Valls said on Twitter.
The attack is the latest in a string of deadly assaults in Europe.
In France, the Normandy attack comes 12 days after a 31-year-old Tunisian Mohamed Lahouaiej Bouhlel ploughed his heavy goods truck into a crowd of revellers in the French Riviera city of Nice, killing 84 people. ISIS claimed that attack.
The knifemen launched their assault by taking five people hostage inside the church in the Normandy town of Saint-Etienne-du-Rouvray, south of Rouen.
Interior Ministry spokesman Brandet confirmed one of the hostages had been killed and said another was critical.
French President Francois Hollande was on his way to the site of the attack.
"Horror. Everything is being done to trigger a war of religions," tweeted Jean-Pierre Raffarin, a former conservative prime minister who now heads the Senate's foreign affairs committee.
