At least seven Nigerian soldiers have been confirmed killed after a deadly ambush by Boko Haram terrorists in Borno State. The affected soldiers were attached to the 153 Task Force Battalion in Marte Local Government Council of the state, sources familiar with the matter told PREMIUM TIMES. According to the sources, the troops were caught by surprise when the terrorists swooped on them at 10 a.m. on Monday. They, however, put up a strong fight to defend their base and ward off the insurgents. But despite their gallant efforts, the soldiers were overwhelmed “because they could not withstand the superior firepower of the terrorists”, our sources said. The unit, which was totally dislodged, has now been moved to Dikwa, another local government area, a development that has now opened up Marte to further attacks. To this end, the army authorities have issued advisories to troops in Sector 3 (especially those in Baga, Cross Kauwa, Kekeno and Monguno and the areas surrounding Marte) to be on red alert. Monday’s attack on Marte Local Government by the extremist Boko Haram group makes it the third onslaught on the area in a month, military insiders said.
