The Latest on the southern France attack (all times local):

4 p.m.

The pope has condemned the attacks in southern France, while lauding the "heroic act" of the French policeman who died after taking the place of a supermarket employee held hostage by an Islamic extremist.

Pope Francis has sent a telegram offering condolences for the loss of life in the attacks, and sympathy to the injured and their families and all those affected. He added: "I particularly welcome the generous and heroic act of Lt. Col. Arnaud Beltrame, who gave his life to protect people."

The pope said that "I condemn such acts of indiscriminate violence which cause so much suffering, and fervently ask God for the gift of peace."

The rampage Friday claimed four victims, including Beltrame, two others in the supermarket and a carjacking victim. The Morocco-born attacker was killed by police when they stormed the supermarket, with Beltrame's help.

A French judicial official says the partner of the Islamist extremist who carried out an attack last week in southern France was, like him, known to police as radicalized.

The 18-year-old woman was still being detained Monday by police for questioning in the case, as well as a 17-year-old friend of gunman Radouane Lakdim, the official said. He was speaking anonymously to discuss the ongoing investigation.

Lakdim was known to police for drug-dealing, and since 2014 had been on the so-called "Fiche S" list, a government register of individuals suspected of being radicalized but who have yet to perform acts of terrorism.

Four people were killed in a carjacking and the supermarket attack Friday near the city of Carcassonne.

Lakdim was killed by police who stormed the supermarket.
