I apologize for the confusion. The Rwandan genocide was a horrific event, with widespread violence and mass killings taking place over a relatively short period of time. The planning leading up to the genocide involved a mix of long-standing tensions, propaganda, and political manipulation.

While it's difficult to pinpoint an exact timeline for the planning phase, there were certainly underlying tensions between ethnic groups in Rwanda that had been present for many years. The immediate catalyst for the genocide can be traced back to April 6th, 1994 when President Juvénal Habyarimana's plane was shot down. This event served as a trigger that set off widespread violence across the country.

The subsequent organized killings were carried out by Hutu extremists who had been preparing for this opportunity with weapons stockpiling and propaganda campaigns targeting the Tutsi minority population.

It's worth noting that discussions surrounding such tragic events require sensitivity and respect towards those affected by them. If you have any other questions or would like to discuss different topics, feel free to ask!
