The Boko Haram attack on Gamboru on May 5–6, 2014, and its twin town of Ngala killed at least 300 people. Some residents reported that they planned to move to Cameroon in the wake of the attacks, and a Nigerian Army source indicated that corruption was hampering efforts to defend local residents.
On May 9, 2014, it was reported that the bridge linking Gamboru to the rest of Nigeria, and also linking "the immigration checkpoints of both Cameroon and Nigeria," had been destroyed. On May 11 it was reported that Borno State Governor Kashim Shettima had visited the town to view the destruction and offer condolences, and "promised to rebuild the Gamboru Ngala central market." Local government chairman Bakura Mustapha indicated that over 200 vehicles, and "hundreds of shops and houses" had been burned.
On 2 February 2015, the Nigerian Army said it had recaptured Gamboru from Boko Haram, along with the nearby towns of Mafa, Mallam Fatori, Abadam, and Marte, following joint military operations by Nigerian and Cameroonian forces, civilian forces, and three days of Chadian airstrikes.
