Boko Haram fighters, disguised as herders, killed at least 20 Cameroonian troops in a Tuesday morning raid on the Nigerian border town of Wulgo.
The Cameroonian military is engaged in a multi-country coalition to fight Boko Haram militants.
Cameroonian troops are commonly stationed across the border in Nigeria as part of anti-jihadist operations around Wulgo, which is near the volatile Lake Chad — home to both Islamic State and Boko Haram fighters.
The militants had disguised themselves as herders and traders in a nearby city and then infiltrated Wulgo to attack its surrounding military positions, said two intelligence sources.
The sources were assisting troops in the long-running fight against the militants and requested anonymity to speak freely.
