Nigerian security forces killed at least 30 gunmen during a joint police and military response to attacks on villages in the country’s northwest, Katsina state authorities said. Three police officers and two soldiers were also killed during the counter-operation, according to State Commissioner for Home Affairs Nasir Mua’zu.

The fighting followed raids by hundreds of armed men on several communities on Tuesday evening. Police and military personnel launched their response on Wednesday, Mua’zu said in a statement released the following day. The supplied account did not identify the villages, give a civilian casualty total or explain how authorities calculated the number of gunmen killed.

The episode was part of a broader security crisis affecting northwestern and north-central Nigeria. Armed groups commonly described as bandits have repeatedly attacked rural communities and travellers, killing residents and abducting people for ransom. Limited security coverage across the mineral-rich northwest has allowed dozens of such groups to operate on village roads and in areas where state forces have struggled to maintain a lasting presence.

Ransom kidnappings provide the groups with income and can also help them exert control over communities. The gangs are distinct from the Islamist insurgency concentrated in northeastern Nigeria, although both conflicts stretch the federal government’s security capacity. Many northwest armed groups include former herders whose disputes with settled communities developed into wider cycles of violence and criminal activity.

Authorities have reported an increase in attacks in the northwestern and north-central regions during recent months, with hundreds of people killed or injured. The five security-force deaths in the latest operation showed the risks involved even when government forces inflicted substantial losses on an attacking group. Mua’zu said the state was working with federal security agencies to protect residents, but his statement offered no immediate indication that all assailants had been captured or driven from the wider area.

Nigeria is simultaneously contending with the long-running insurgency in its northeast. According to United Nations figures cited in the supplied report, that conflict has killed about 35,000 civilians and displaced more than two million people. The northwest violence has different origins and participants, but it has compounded the national burden through mass killings, raids and abductions.

The Katsina operation therefore represented a significant tactical confrontation rather than evidence that the region’s broader banditry problem had been resolved. Immediate facts came from state authorities, and no independent casualty verification was included in the available evidence. Further reporting would be needed to establish civilian losses, property damage and the security situation in each community after the fighting. Further assessment was also needed to determine whether displaced residents could safely return.
