Nigeria's Minister of Defence, Mohammed Badaru Abubakar, has resigned from his position, citing health reasons, amidst a critical security crisis. The 63-year-old's departure comes as the country grapples with a surge in mass kidnappings, raising concerns about the effectiveness of the government's response. The UN High Commissioner for Human Rights reported a staggering 402 kidnappings, primarily involving schoolchildren, since mid-November. The latest incident involved gunmen abducting at least 20 people, including a Christian pastor, a Muslim bride, and her bridesmaids, in two separate raids in the north. The fate of 250 schoolchildren and 12 teachers from a Catholic school in central Niger state remains uncertain, marking the largest mass kidnapping in recent memory. The identity of the kidnappers is still unclear, with analysts attributing the crimes to criminal gangs seeking ransom, while a presidential spokesman suggests jihadist groups may be involved. Abubakar's resignation letter to President Bola Tinubu provides no specific health details, but the timing coincides with a critical juncture in Nigeria's security landscape. President Tinubu has declared a national security emergency, planning to expand the police force by 20,000 officers. Nigeria's security challenges are multifaceted, encompassing ransom kidnappings, Islamist insurgency, separatist violence, and land disputes between herders and farmers. Abubakar's tenure as governor of Jigawa state from 2015 to 2023 and his role in Tinubu's presidential campaign make his resignation a significant development. The President is expected to announce Abubakar's successor and address the Senate this week, marking a pivotal moment in Nigeria's ongoing struggle with security threats.
