Rwandan genocide financier and suspect Félicien Kabuga has died in hospital in The Hague, bringing to an end one of the longest-running international manhunts tied to the 1994 genocide against the Tutsi tribe in Rwanda.

His death was confirmed Friday by the United Nations International Residual Mechanism for Criminal Tribunals, which said Dutch authorities had begun routine legal procedures and investigations following his death.

The tribunal’s president, Judge Graciela Gatti Santana, directed that a separate review be carried out into the circumstances surrounding Kabuga’s final days. Judge Alphons Orie has been tasked with leading the inquiry.

Kabuga, who was in his 90s, had been awaiting relocation to a country willing to receive him after the court considered releasing him on humanitarian grounds due to his worsening health condition.

For years, Kabuga remained one of the most sought-after suspects connected to the Rwanda genocide, in which more than 800,000 people predominantly Tutsis and moderate Hutus were killed within 100 days.

Prosecutors accused him of playing a major role in financing the killings and spreading ethnic hatred. He faced charges ranging from genocide and conspiracy to commit genocide to extermination, persecution and murder as crimes against humanity.

An international arrest warrant was issued against him by the International Criminal Tribunal for Rwanda in 2013, though he had successfully evaded authorities for decades.

Kabuga was eventually arrested near Paris in France in May 2020 and later transferred to The Hague for trial proceedings.

His trial opened in September 2022 but was halted a year later after judges found him medically unfit to continue participating in the case.
