What event seems to precipitate the genocide in hotel Rwanda?

The genocide in "Hotel Rwanda" is precipitated by the assassination of Rwandan President Juvénal Habyarimana on April 6, 1994, when his plane was shot down. This event triggered widespread violence as extremist Hutu factions blamed the Tutsi minority for the attack, leading to the systematic killing of Tutsis and moderate Hutus. The assassination ignited long-standing ethnic tensions and resulted in a rapid escalation of atrocities throughout the country.
