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.
Hundreds of heavy duty trucks plying the Chad-Nigeria highway along Gamboru-Ngala Local Government conveying commodities from the two countries are now left stranded on either sides of the bridge.
On May 11, 2014, 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 May 13, 2014, the House of Representatives noted that this was the third attack on Gamboru by Boko Haram, and "called on the Federal Government to rebuild the Gamboru Bridge linking the border town with other parts of Borno State. It also called for increased military presence around Gamboru Ngala."
