Niger’s new military junta has asked for help from the Russian mercenary group Wagner as the deadline nears for it to release the country’s ousted president or face possible military intervention by the West African regional bloc, according to an analyst.

The request came during a visit by a coup leader, Gen. Salifou Mody, to neighboring Mali, where he made contact with someone from Wagner, Wassim Nasr, a journalist and senior research fellow at the Soufan Center, told The Associated Press. He said three Malian sources and a French diplomat confirmed the meeting first reported by France 24.

“They need (Wagner) because they will become their guarantee to hold onto power,” he said, adding that the group is considering the request. A Western military official, speaking on condition of anonymity because they were not authorized to comment, told the AP they have also heard reports that the junta asked for help from Wagner in Mali.

Niger’s junta faces a Sunday deadline set by the regional bloc, known as ECOWAS, to release and reinstate the democratically elected President Mohamed Bazoum, who has described himself as a hostage.

Defense chiefs from ECOWAS member states finalized an intervention plan on Friday and urged militaries to prepare resources after a mediation team sent to Niger on Thursday wasn’t allowed to enter the capital or meet with junta leader Gen. Abdourahmane Tchiani.

On Saturday, Nigeria’s Senate advised the nation’s president, the current ECOWAS chair, to further explore options other than the use of force to restore democracy in Niger, noting the “existing cordial relationship between Nigeriens and Nigerians.” The legislators had deliberated on the president’s request informing them of ECOWAS’ decisions and Nigeria’s involvement, as required by law.

Final decisions by ECOWAS, however, are taken by a consensus among its member countries.

After his visit to Mali, run by a sympathetic junta, Mody warned against a military intervention, vowing that Niger would do what it takes not to become “a new Libya,” Niger’s state television reported Friday.
