The Nigerian Navy says it has dismantled a sophisticated explosives factory during a high-stakes clearance operation in the restive Orsu local government area of Imo State.

The raid, conducted by a tactical squadron from the Oguta Naval Base, targeted a notorious insurgent stronghold known as “Mother Valley.” Naval officials confirmed that the site was being used by the outlawed Indigenous People of Biafra (IPOB) and its armed wing, the Eastern Security Network (ESN), to manufacture Improvised Explosive Devices (IEDs).

In a coordinated ambush at the facility, naval personnel “neutralized” two specialists responsible for assembling the bombs.

A ‘hidden’ minefield

The operation was described by military sources as high-risk, as troops encountered multiple active IEDs planted along the Orsu–Ihiteukwa axis. Specialist teams were brought in to destroy the recovered explosives in situ to prevent any accidental civilian casualties.

“The discovery of an active IED-making facility confirms the presence of a structured explosive network,” said Navy Captain Abiodun Folorunsho. He added that all naval personnel and equipment returned from the “Mother Valley” intact.

Analysis: The shift to asymmetric warfare

The use of IEDs marks a significant escalation in the conflict in southeast Nigeria. While the region has seen years of hit-and-run attacks on police stations and government offices, the transition to manufacturing landmines and roadside bombs suggests the insurgents are adopting more “asymmetric” tactics often seen in the country’s northeast.

For the Nigerian Navy, which traditionally focuses on maritime security and oil theft in the Niger Delta, this land-based tactical raid in Imo State highlights the increasing “joint-force” approach required to manage internal security.

By taking out the “bomb-makers” rather than just the foot soldiers, the military hopes to significantly degrade the rebels’ ability to launch large-scale ambushes on security convoys. However, the “Mother Valley” remains a dense and difficult terrain, and maintaining a permanent security presence there will be the next major challenge for the Abuja administration.
