The Islamic State of West African Province (ISWAP) has killed six locals in Borno state with a landmine they planted.
ISWAP planted the Improvised Explosive Devices along Gamboru-Ngala road in Ngala Local Government Area of Borno state.
A humanitarian worker disclosed to the media on Tuesday, that the first incident on Monday February 14 involved a commercial pickup vehicle in which three persons died at the spot.
The second IED killed two members of the local vigilantes who arrived at the scene to offer assistance for the injured victims.
According to the source, one member of the Civilian Joint Task Force patrolling the Maiduguri-Gamboru Ngala federal highway was also shot dead while one other was injured.
The Gamboru-to-Maiduguri highway is said to be a strategic 140-kilometre (87-mile) trade route in the region, and provides an important link with neighbouring Cameroon.
Governor Babagana Zulum re-opened the federal highway last week after three years of shut down and had spent three days with the returnees in Gamboru and Wulgo communities to personally distribute cash, food and non-food items for the returnees.
