Operations at Diori Hamani International Airport in Niamey are continuing normally following security incidents in the Nigerien capital overnight from Friday to Saturday, the National Agency of Civil Aviation said on Saturday.

In a letter to the heads of various airport-related agencies, Hamadou Ousseini Ibrahim, director general of the civil aviation agency, urged them to "ensure the continuity of services under their respective structures."

The announcement came after gunfire and explosions were heard in several parts of Niamey overnight, including near Diori Hamani International Airport and the presidential palace, according to witnesses and several international media outlets.

Niger's Ministry of National Defense said Saturday that it had contained an attempted mutiny involving a group of soldiers at Air Base 101, located near the international airport.

According to a ministry statement read out on national television, a group of soldiers in breach of military regulations attempted to detain some of their fellow soldiers at the base and opened fire at several sites in the capital. The prompt response by the defense and security forces reportedly helped contain the mutiny attempt and gradually restore control over the sites concerned.

Authorities called on the public to remain calm and continue their activities as normal.
