Foreign hostages in Nigeria
Since 2006, militant groups in Nigeria's Niger Delta, especially the Movement for the Emancipation of the Niger Delta (MEND), have resorted to taking foreign employees of oil companies hostage as part of the conflict in the Niger Delta. More than 200 foreigners have been kidnapped since 2006, though most were released unharmed.
