A Greek Orthodox priest was shot at a church in Lyon, France, at about 4 p.m. local time Saturday.
The priest, identified by French police as Nikolas Kakavelakis, was in critical condition, a spokesperson for the national police said. He is in care at a hospital, police said.
A search was underway for the assailant. One arrest had been made, but it is unclear if the arrested person is the shooter, according to police.
Two gunshots were fired from a hunting rifle, police said.
"An event is underway near the Jean-Macé sector, in the 7th arrondissement in Lyon," the French Interior Ministry wrote on Twitter early Saturday afternoon. "Security and rescue forces are there. A security perimeter has been installed."
The ministry added that people should avoid the area.
This attack comes as the nation is on high-alert after a terror attack at the Basilica of Notre-Dame in Nice this week.
French authorities are monitoring the Lyon shooting but have not qualified it as an act of terrorism.
