Rwanda's government is to reveal details of a report containing allegations of French involvement in the country's 1994 genocide.
Rwanda has accused France of playing an active role in the genocide of 1994, in which about 800,000 people were killed.
The report is expected to contain the names of those alleged to be implicated and the accusations against them.
A justice ministry report said France was aware of preparations for the genocide and helped train the ethnic Hutu militia perpetrators.
Some 800,000 people were killed in just 100 days in the 1994 massacre.
The report also accused French troops of direct involvement in the killings.
Earlier this year France's foreign minister denied French responsibility in connection with the genocide, but said political errors had been made.
It named 33 senior French military and political figures that it said should be prosecuted. France has previously denied any such responsibility.
Among those named in the report were the late former president, Francois Mitterrand, and two former prime ministers, Dominique de Villepin and Edouard Balladur.
Also named was former Foreign Minister Alain Juppe.
The French foreign ministry told the BBC it would only respond to the fresh allegations after reading the report, which was released on Tuesday afternoon.

Some 800,000 minority Tutsis and moderate Hutus were slaughtered by Hutu militias in just 100 days in 1994.
The report says France backed Rwanda's Hutu government with political, military, diplomatic and logistical support.
It accuses France of training Hutu militias responsible for the slaughter, helping plan the genocide, and participating in the killings.
"French forces directly assassinated Tutsis and Hutus accused of hiding Tutsis... French forces committed several rapes on Tutsi survivors," said a statement from the justice ministry cited by AFP news agency.
"Considering the seriousness of the alleged crimes, the Rwandan government has urged the relevant authorities to bring the accused French politicians and military officials to justice," the statement said.
It further alleged that French forces did nothing to challenge checkpoints used by Hutu forces in the genocide.
"They clearly requested that the Interahamwes contine to man those checkpoints and kill Tutsis attempting to flee," it said.
