On the 50th anniversary of the massacre, survivors of the massacre are seeking action from Burundi.

Survivors of a wave of ethnic atrocities in Burundi fifty years ago are pleading with the government to do more to address the violence's legacy.

In the mass killings that began on April 29, 1972, up to 300,000 people died.

The conflict stemmed from long-standing hostilities between the Hutu and Tutsi ethnic groups, who dwell in Burundi and Rwanda, respectively.

Hutu comprised the majority of the victims.

The killings, according to a truth and reconciliation committee that has been exhuming mass graves since the time, amounted to genocide.

The 1994 Rwanda genocide, which killed about 800,000 Tutsis over 100 days, was the greatest outbreak of violence between the two factions.
