In which one of the following countries did an ethnic violence between the communities of Hema and Lendu result in the death of hundreds of people?

The conflict between the Hema and Lendu ethnic groups primarily takes place in the Ituri province of the Democratic Republic of Congo. This long standing violence is rooted in disputes over land, resources, and political power. The tension between these communities has historically led to several waves of mass killings and internal displacement, most notably during the Ituri conflict and more recently in renewed clashes over the past few years. While ethnic tensions exist in other African nations, the specific Hema-Lendu rivalry is unique to the Democratic Republic of Congo.
