In the years since Rwandan national and former Congolese General* Bosco Ntaganda was indicted by the International Criminal Court, accused of committing horrific war crimes and crimes against humanity during the Democratic Republic of Congo's civil war in 2002 and 2003, he has acted more or less with impunity. He's been accused of running his little corner of the Congo as a mafia-style fiefdom, participating in smuggling and the conflict minerals trade.

On Monday, for reasons that are still mysterious, he walked into the U.S. embassy in Kigali, Rwanda, and asked to be transferred to the ICC for trial.

It's difficult to fully capture Ntaganda's hard-earned reputation for brutality, his role in some of Central Africa's darkest moments, the legacy of horror he leaves behind. But this six-minute video, produced by Human Rights Watch, provides a helpful understanding of who he is, why he matters and what made him such a uniquely frightening figure.

We'll have more on Ntaganda soon so, please do check back.

* – An earlier version of this post described Ntaganda as a “Rwandan general.” A number of readers, understandably, took this as implying that Ntaganda is a general in the Rwandan military. He is not; he is a Rwandan national who also served, presumably until he led a rebellion in April, as a general in the Congolese military. I regret causing any confusing.
