KIGALI, RWANDA -- France "bears significant responsibility" for enabling the genocide in Rwanda and still refuses to acknowledge its true role in the 1994 horror, said a report commissioned by Kigali that was released Monday.

The damning report, commissioned in 2017 and running to nearly 600 pages, labels France a "collaborator" of the extremist Hutu regime that orchestrated the pogrom of some 800,000 people, and outright rejects the position that Paris was blind to their genocidal agenda.

The years-long investigation by U.S. law firm Levy Firestone Muse said France knew a genocide was coming but remained "unwavering in its support" of its Rwandan allies, even when the planned extermination of the Tutsi minority was clear.

"It is our conclusion that the French government bears significant responsibility for enabling a foreseeable genocide," states the Muse report, which drew on millions of pages of documents and interviews with more than 250 witnesses.  

It found no evidence, however, that French officials or personnel directly participated in the killing of Tutsis.

France has long been accused of not doing enough to halt the massacres, and the Muse reports follows the publication last month of a separate inquiry into the same events commissioned by French President Emmanuel Macron.

The Duclert Commission, named after the historian leading that investigation, concluded that France bore "overwhelming responsibilities" over the genocide and acknowledged a "failure" on its part, but no complicity in the killings.

But the Muse report asserts greater French culpability, saying the Duclert Commission stopped short of explaining what France was responsible for, and erred in concluding that Paris "remained blind" to the looming genocide.

"The French government was neither blind nor unconscious about the foreseeable genocide," the report stated. 

More than a quarter of a century on the issue still poisons relations between France and Rwanda under President Paul Kagame, a former Tutsi rebel who has ruled the mountainous nation in Africa's Great Lakes region since the aftermath of the genocide.

'Indispensable collaborator'

The genocide between April and July of 1994 began after Rwanda's Hutu president Juvenal Habyarimana, with whom Paris had cultivated close ties, was killed when his plane was shot down over Kigali on April 6.

Within a few hours extremist Hutu militia began slaughtering Tutsis, and some moderate Hutus, with a scale and brutality that shocked the world.

Victims were felled with machetes, shot, or massacred while seeking shelter in churches and schools, while sexual violence was rife.

The Muse report said nobody worked closer with Habyarimana than France under then leader Francois Mitterrand, who was most to blame for the "reckless enabling" of the radical Hutu regime as it prepared for genocide.

France provided critical military and political support to the regime to protect its own strategic interests in Africa, the report said, and ignored internal warnings of a looming slaughter even as hateful rhetoric and violence against the Tutsi surged.

"Only the French government was an indispensable collaborator in building the institutions that would become instruments of the genocide. No other foreign government both knew the dangers posed by Rwandan extremists and enabled those extremists..." the report states.

"The French government's role was singular. And still, it has not yet acknowledged that role or atoned for it."

Kagame welcomed the recent Duclert Commission as "an important step toward a common understanding of what took place" but said a decades-long effort by France to avoid responsibility had caused "significant damage".

The Muse report accused France of concealing documents, obstructing justice and spreading falsehoods about the genocide in a deliberate campaign to "bury its past in Rwanda".

"The cover-up continues even to the present," the report added, saying French authorities refused to cooperate with their inquiry or turn over critical documents pertinent to their investigation.

Rwandans for too long "have watched the French government avoid the truth and fail to acknowledge its role and responsibility", it stated.

On April 7 -- the 27th anniversary of the start of the genocide -- France ordered the opening of key archives concerning the work of Mitterrand between 1990 and 1994, including telegrams and confidential notes that were sources in the Duclert investigation.

The Muse report noted that the recent disclosure of some documents related to the Duclert Commission suggested "a move toward transparency".
