French President Emmanuel Macron has appointed a panel of experts to investigate France’s role in Rwanda’s genocide 25 years ago.
An estimated 800,000 Rwandans, most from the minority Tutsi community, were killed by ethnic Hutu extremists over 100 days in 1994.
Rwanda has accused France of complicity in the mass killings – a charge repeatedly denied by Paris.
The experts will now consult archives to analyse France’s role.
They will have access to presidential, diplomatic, military and intelligence archives, Mr Macron’s office said in a statement.

Former president Francois Hollande announced that the archives would be declassified in 2015, but two years later, after a researcher sought permission to study them, France’s Constitutional Council ruled that they should remain secret.
The constitution says papers deposited in the archives by a president or minister can remain secret for 25 years after that person’s death. The president at the time of the genocide, Francois Mitterand, died in 1996.
What is the purpose of the investigation?
Looking at the period from 1990 to 1994, it is hoped that the findings made by the eight historians and researchers will “contribute to a better understanding and knowledge” of what happened, the presidency said.
“The goal is to deliver a report which will be published in two years time… and will be accessible to all,” it added.
France was a close ally of the Hutu-led government of Juvenal Habyarimana prior to the massacres.
It was the shooting down of his plane over the capital Kigali in April 1994 that triggered the genocide.
Rwanda has accused France of ignoring or missing warning signs and of training the militias who carried out the attacks.
It also says French forces, stationed there as part of a UN peacekeeping operation, used the creation of a safe zone to help some of the perpetrators to escape.
The issue has long strained relations between the two countries, though they have improved over the past decade.
Mr Macron turned down an invitation to attend genocide commemorations in Rwanda this weekend, citing scheduling problems.
