On 25 September, a second Russian cargo plane landed in Nampula province and unloaded large-calibre weapons and ammunition belonging to the Wagner Group, which were then transported to the Cabo Delgado province where, since 5 October 2017, an Islamist insurgency had been taking place. At least one of the two cargo planes belonged to the 224th Flight Unit of the Russian Air Force. Overall, 200 PMCs, including elite troops, three attack helicopters and crew arrived in Mozambique to provide the training and combat support in Cabo Delgado, where the Islamist militants had burned villages, carried out beheadings and displaced hundreds of people.
