At least 23 fighters belonging to rival Boko Haram and Islamic State West Africa Province (ISWAP) factions have reportedly been killed in a fresh battle for territorial control in Sambisa Forest, Borno State.

The latest confrontation occurred around the Chingolo axis of Bama Local Government Area, where Boko Haram fighters reportedly engaged ISWAP members who had advanced into the area.

Security sources familiar with developments in the region said the renewed hostilities had persisted for about two days, with both groups battling to consolidate their positions and deny the other access to strategic areas within the forest.

According to security analyst and counter-insurgency expert, Zagazola Makama, the clash involved prolonged exchanges of gunfire as the rival factions fought over territory, access routes and operational space.

Preliminary intelligence indicated that more than 23 fighters from both sides had been killed since the latest round of fighting began.

However, the exact breakdown of casualties suffered by Boko Haram and ISWAP could not be independently established.

The latest confrontation is believed to be part of the longstanding rivalry between the two insurgent groups, which has periodically erupted into violent clashes over territory, resources, fighters and influence in the North-East.

Sources said the fighting escalated after ISWAP fighters reportedly moved towards the Chingolo axis, prompting Boko Haram elements operating in the area to launch an offensive.

The ensuing battle reportedly left casualties on both sides and disrupted the activities of the insurgent groups in parts of Sambisa Forest, one of the key areas historically associated with Boko Haram operations.

Footage purportedly showing aspects of the confrontation has also emerged, although its authenticity, location and the circumstances under which it was recorded could not be independently verified.

The renewed infighting comes amid sustained military operations against insurgent groups in the North-East, with security forces continuing efforts to dismantle terrorist hideouts, logistics networks and fighter concentrations.

Security sources said intelligence agencies were monitoring developments and tracking the movements of the rival factions following the latest confrontation.

The renewed rivalry could further strain the operational capacity of both groups as they divert personnel and resources towards fighting each other rather than security forces and civilian targets.

Communities around Sambisa Forest have consequently been advised to remain vigilant and promptly report suspicious movements or activities to security agencies.
