Suspected Boko Haram militants have seized a military base in the northeast Nigerian town of Baga.
Local residents said the armed Islamist group overwhelmed troops after an hours-long battle at the facility near Lake Chad.
Soldiers and civilians reportedly fled the area following multiple attacks on Saturday.
The base is used by a multinational task force mandated to fight transnational crime and and incursions. It includes soldiers from Nigeria, Chad and Niger.
Few other details were immediately available.
Boko Haram has been blamed for thousands of deaths during its five-year insurgency in Nigeria.
