France has admitted responsibility for the torture and killing of a communist activist in Algeria over 60 years ago, BBC reports.
Maurice Audin, 25, was working as a mathematician at the University of Algiers when he was arrested in 1957.
In a rare admission on Thursday, French President Emmanuel Macron said Audin had either been tortured to death or tortured and executed during French colonial rule.
Algeria gained independence from France in 1962 after a bloody seven-year war.
Audin was one of the few Europeans in the country to support Algerian calls for independence when he disappeared during the Battle of Algiers. He was married with three children.
President Macron is due to pay a formal visit to Audin's widow on Thursday, as well as to open the archives "on the subject of disappeared civilians and soldiers, both French and Algerian".
