More than 40 gunmen, many of whom arrived in trucks or on foot to avoid security checks, pretended to be ordinary traders and infiltrated the weekly market in Gajiram (also spelled Gajiran), headquarters of Nganzai LGA, about 75–85 km north of Maiduguri. Once inside, they opened fire indiscriminately on shoppers and sellers, killing 15 people. The attackers also set fire to the local government secretariat, a primary school, a police station and a clinic, as well as residential houses belonging to local politicians.

Response
The military’s 5 Brigade, 7 Division (Monguno) pursued the attackers to camps in Marte and Sambisa forests, killing about 50 insurgents in a shootout and destroying the camps with air support. The Borno State attorney‑general, the state police commissioner and the chairman of Nganzai LGA visited Gajiram to condole with families and assess damage. Vigilante groups (Civilian JTF) helped repel the initial attack.

Cycle notes
The Gajiram market attack directly echoed the 5 April 2012 Maiduguri “Monday Market” attack (7 killed), where gunmen opened fire on a crowded commercial hub. By 2013 the tactic had become more refined: the Gajiram attackers arrived at about 10 a.m. and systematically torched the local government secretariat, two primary schools, a clinic, and several homes – a level of destruction that mirrored the scorched‑earth tactics seen in the 16‑17 April 2013 Baga massacre (2,275 homes razed), but perpetrated by insurgents rather than state forces. The reprisal motive was made explicit by a witness: “they attacked us because of how our volunteers have succeeded” – a pattern repeated in the 27 July 2013 Dawashe massacre (20+ killed) and the 30 August 2013 Monguno ambush (24 vigilantes killed), demonstrating a sustained insurgent strategy of collective punishment against communities that cooperated with the Civilian JTF. The attack also foreshadowed later market massacres, such as the 19 May 2014 Kano suicide bombing (5 killed) and the 10 January 2015 Maiduguri market suicide bombing (at least 16 killed), establishing markets as recurring soft targets across the Northeast.

Boko Haram insurgents launched a brazen attack on a Nigeria Customs Service office in Geidam town, Yobe State. The assailants arrived in a Volkswagen Golf and a Land Rover, with some also on motorbikes, storming the Customs house located along the Maine Soroa Road. They began firing indiscriminately, and some witnesses reported they were shouting “Allahu Akbar” as they attacked. The Customs officers, taken by surprise after many had retired for the night, scrambled for safety—some escaping through the gate, while others scaled the fence. In the chaos, one officer, Assistant Superintendent of Customs II Ahmed Usman (also referred to as Usman Gombe), was shot dead while trying to climb the fence. The attackers also set fire to a Customs patrol van, a generator, and part of the office building. However, timely reinforcement from the Nigerian Army helped security personnel repel the assault and prevent further casualties.
Boko Haram gunmen killed 12 nomads in Dumba village, Damboa District, Borno State. The nomads had stormed a Boko Haram hideout to avenge the killing of two herders during a previous insurgent attack on Yaguwa village. The confrontation escalated into a firefight, leaving the nomads dead.
Boko Haram fighters, dressed in military uniforms and driving vehicles painted in army colors, approached the base from Gubio in neighboring Borno State. The soldiers at the base, expecting reinforcements from their colleagues in Gubio, mistook the attackers for friendly troops and opened the gates. Once inside, the insurgents launched a fierce attack. The soldiers tried to fight back but were overwhelmed by the attackers' superior firepower, which included anti-aircraft guns, while the troops were limited to AK-47 rifles and unreliable machine guns.
