Answer:
The correct answers are A and B. The presidents of Rwanda and Burundi were killed in a mysterious plane crash.
Step-by-step explanation:
On the afternoon of April 6, 1994, the presidential plane carrying Rwandan President Juvenal Habyarimana and Burundian President Cyprien Ntaryamira, both Hutu, was shot down by surface-to-air missiles as it prepared to land in Kigali (Rwanda). The murder launched two of the bloodiest events of the late twentieth century: the Rwandan genocide (April-July 1994) and the First Congo War (1996-1997).
