In the first joint operation between the two countries, troops from Burkina Faso and the Ivory Coast have taken out an Islamic jihadist military base in Alidougou in southern Burkina Faso. The attack was part of Operation “Comoe,” an ongoing effort to stop the spread of Islamic terror that is gripping the region.

Operation “Comoe” is named after a river that separates the two African countries. It was launched earlier in May.

Soldiers killed eight suspected militants and arrested 38 others, 14 in Ivory Coast and 24 in Burkina Faso, according to a statement released by the Ivory Coast’s military. In addition, the joint counter-terrorism operation, supported by helicopter gunships, succeeded in seizing automatic weapons, ammunition, motorcycles, and mobile phones. The statement praised the “perfect coordination between the two armies.”

Burkina Faso is part of the G5 Sahel nations that are battling increasingly violent Islamist insurgent forces in the semi-arid Sahel region. The insurgents are linked to both al-Qaeda and the Islamic State.
