Tensions are rising in West Africa as Chad has closed its border with Nigeria, citing security concerns tied to alleged U.S. military intentions in the region.

The decision follows controversial comments by U.S. President Donald Trump, who recently hinted at possible military action in Nigeria. His remarks have triggered widespread unease across the sub-region, with governments responding cautiously.

Chadian authorities say the border closure is a preventive measure to protect national security while monitoring unfolding developments.

The move adds to growing instability in the Lake Chad Basin, where security dynamics remain fragile and highly sensitive to geopolitical shifts.
