At about 00:20 on 29 August, serving soldiers at Base 101 detained comrades inside the barracks and opened fire on sensitive sites in Niamey [E1]. Niger’s Defence Ministry described the perpetrators as soldiers who had broken military regulations and said security forces began progressively recovering the targeted sites [E1]. Defence Minister Salifou Modi later said he had taken control of the unrest, while sporadic firing continued in the capital [E2]. The official classification was a military mutiny originating inside Base 101 [E2][E3].
Radio and television signals were interrupted during the violence, and RTN programming resumed at about 10:00 on 29 August [E2]. The Confederation of Sahel States called the episode a mutiny and said loyalist Nigerien security forces had contained and defeated the attempt [E3]. Its statement credited forces that remained loyal with restoring order after attacks on Base 101 and other sensitive sites [E3]. The presidency stayed in loyalist hands through 30 August, when Russia’s Foreign Ministry said the situation was controlled by the lawful authorities headed by Abdourahamane Tiani [E5].
The disturbance reached the airport complex without shutting civilian aviation. Niger’s civil-aviation authorities said operations across Diori Hamani International Airport continued normally on 29 August despite events affecting the airport [E4]. Base 101 sits within that airport area, placing the mutiny beside one of the capital’s most sensitive transport and military nodes [E4]. By the end of the day, the government and the AES were describing the uprising as contained and the affected sites as returning to loyalist control [E1][E3].
Moscow said on 30 August that the attacks were repelled by Nigerien national troops with assistance from servicemen of the Russian Defence Ministry’s Africa Corps [E5]. That wording assigns the repelling of the attacks to Nigerien forces and describes the Russian role as assistance [E5]. The statement does not say Africa Corps units recaptured Base 101 [E5]. It also said Tiani’s authorities remained in control, tying Russia’s intervention claim to support for an existing government command structure [E5].
Algeria entered the picture on 30 August with an overt military deployment requested by Nigerien authorities. Algeria’s Defence Ministry said it ordered two patrols of Su-30 fighters, four aircraft in total, on a support mission for the Nigerien army after the Niamey events [E6]. The ministry said the four fighters and an aerial-refuelling aircraft landed at Niamey that morning [E6]. Its statement contains no claim that the fighters fired weapons or flew combat sorties [E6].
The Nigerien account identifies the accompanying tanker as an Ilyushin Il-78 and says the four fighters made an aerial parade before landing [E7]. Prime Minister Ali Mahaman Lamine Zeine attended the reception alongside senior defence and government officials [E7]. Tiani was not listed among the reception party; Zeine said the president had charged him with going to see the aircraft [E7]. Russia’s statement separately identified Tiani as still heading Niger’s lawful authorities on 30 August [E5].
By 30 August, Base 101 and the capital’s sensitive sites were back under government control, civilian airport operations were continuing, and the AES was publicly saluting the loyalist response [E1][E3][E4]. Russia’s own record says Africa Corps assisted Nigerien troops, and it goes no further [E5]. Algeria’s own record establishes four Su-30s and a tanker landing at Niger’s request, while the Nigerien account names the tanker as an Il-78 [E6][E7]. The soldiers who fired into Niamey’s sensitive sites ended the episode with Base 101 back in loyalist hands [E1][E3].
