A total of 1,932 people were killed in Borno, Adamawa and Yobe between April and June 2026 as bandits, terrorists and other non-state armed groups continued violent attacks across the region.
The figures came from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) in its 2026 Second Quarter Humanitarian Access Snapshot for the three states. The report was compiled by the Humanitarian Access Working Group using data from the Armed Conflict Location and Event Data Project and the UN Mine Action Service.
OCHA said attacks involving improvised explosive devices dropped from 65 to 54, a 16.9 per cent fall. Civilian casualties linked to explosive ordnance and IEDs also dropped from 163 to 54, a 66.9 per cent decline.
The agency linked the drop to joint operations by Nigerian and U.S. forces in northern and central Borno and lower civilian movement because of worsening insecurity.
“The high-tempo nature of US and AFN military operations witnessed during this period contributed to a reduction in IED/EO incidents. Additionally, civilians aware of the heightened insecurity and threats by NSAGs moved around less during this period, contributing to a narrowing of the locations affected by IEDs this quarter,” the report stated.
The report also said health and nutrition partners suspended work in Dapchi, Bursari council area, on April 4 after repeated attacks by non-state armed groups.
It added that Nigerian troops repelled attacks on Bazamri village in Konduga council area on May 13 and Alou Dam, a few kilometres from Maiduguri, on May 31.
OCHA also reported 11 airstrikes in Borno during the quarter, with Jilli Market on the border of Gubio and Geidam council areas targeted on April 12. Most of the other strikes were carried out in the Sambisa Forest and Mandara Mountains.
