Nigeria is the fifth-largest supplier of crude oil to the United States. (The United States is Nigeria's biggest single export market.) Behind this lucrative business relationship, however, is a wild backdrop of conflict in Nigeria’s oil fields.

Militants pushing for a share of this oil wealth and environmental remediation have resorted to blowing up pipelines, taking foreign hostages and fighting government troops. Commander Fara Dagogo is a member of the biggest rebel group, the Movement for the Emancipation of the Niger Delta, or MEND. The commander talks with The Takeaway about why he is sabotaging his country’s oil production.
