French President Emmanuel Macron condemned the brutal murder of an elderly Holocaust survivor at her Paris home last week, saying he was determined to "wipe out anti-Jewish sentiment" in France.
The charred body of Mireille Knoll, 85, was found in her Paris apartment on Friday. She had been stabbed 11 times and her home was set on fire.
Authorities said the murder was most likely anti-Semitic in nature.
"I want to express my deep emotion after the dreadful crime committed against Mrs. Knoll. I reaffirm my total determination in fighting anti-Semitism," Macron tweeted.
Knoll escaped the 1942 roundup of more than 13,000 Jews in Paris, who were handed over to the Nazis and sent to death camps.
British news website The Express quoted a judicial source as saying that two suspects had been arrested in the case and have been charged with "murder motivated by the real or supposed adherence to a religion, as well as aggravated theft and damage to property."
One of the two suspects is said to be Knoll's 28-year-old neighbor. He was recently released from prison, where he served an eight-month sentence for the sexual assault of a young girl, the report said.
Knoll's murder has rattled the French Jewish community.
France's Chief Rabbi Haïm Korsia said he was "horrified" by her tragic death.
"The horror of the crime and the violence of the executioners are identical and reflect the negation of the human face. No one is born racist or anti-Semitic," he tweeted.
The Council of French Jewish Institutions called for the "fullest transparency" by the authorities investigating the murder, which it condemned as "barbaric."
France's 400,000-strong Jewish community, which is the biggest in western Europe, has repeatedly expressed concern over the rise of anti-Semitism in the country.
