A 72-year-old religious sister has been praised for her “extraordinary courage” after she sought to disarm a man stabbing a priest at a Catholic church in Nice, southeastern France.

Sister Marie-Claude reportedly intervened after a 31-year-old man entered the Saint-Pierre d’Arene church before Sunday Mass on April 24 and repeatedly stabbed Father Krzysztof Rudziński.

She received a wound to the forearm and was taken to a hospital along with the 57-year-old priest.

The Diocese of Nice said in an April 24 statement that neither the sister nor the priest suffered life-threatening injuries in the incident, which police said was not related to terrorism.
