Liberia Sierra Leone’s President Julius Maada Bio declared a nationwide curfew Sunday after gunmen attacked the military’s main and largest barracks in the West African nation’s capital, raising fears of a breakdown of order amid a surge of coups in the region. The unidentified gunmen attacked the military armory within the Wilberforce barracks in the capital, Freetown, early morning.

The country’s Ministry of Information and Education also said in a statement the government and security forces are “in control” of the situation, and “calm has been restored,” but citizens are encouraged to stay indoors while Security Forces continue to root out the remnant of the fleeing renegades. No details have been immediately given about the gunmen or the reason for the attack.
