Militants from Boko Haram and ISWAP launched coordinated attacks on two Nigerian military bases in Borno State, killing at least 16 soldiers, security sources reported. The assaults occurred in Marte and nearby outposts, with fighters using gunfire and explosives before being repelled. No group immediately claimed responsibility, but the groups have long targeted security forces in their bid to establish an Islamic State. 

Nigeria's military confirmed the incidents, stating reinforcements arrived swiftly to restore control. The violence underscores the persistent insurgency in the northeast, where thousands have died since 2009 and over 2 million remain displaced. Government efforts, including air strikes and troop surges, have weakened the militants but failed to end the threat amid porous borders and arms flows. 

Local leaders called for more equipment and intelligence sharing, while analysts note factional rivalries between Boko Haram and ISWAP fuel ongoing clashes. Rights groups report civilian casualties often go uncounted in the remote area. Abuja vows intensified operations, balancing security with humanitarian aid needs.
