The people of Burundi vote Monday on a new constitution that would require the majority Hutus and minority Tutsis to share governmental power. If the referendum passes, the country would elect a new set of leaders in the next few months.
Uncertainty surrounds both the vote and its possible aftermath. The politically powerful Tutsis have threatened to boycott the referendum, saying the new constitution gives Hutus too much power.
After the central African nation's last election, in 1993, the Hutu president was assassinated, and massacres and a decade-long civil war ensued. Hundreds of thousands were killed.
