Suspected Boko Haram gunmen killed four people on Sunday when they ambushed a car carrying six people in the northeastern Borno state of Nigeria, a civilian joint task force and a military source said.
The military source said that the gunmen attacked the car on the Damboa-Biu road near the Nwajurko village at about 9:30 am (0830 GMT).
"Four of the passengers were shot dead by Boko Haram while two others who fled the ambush sustained injuries partly from gunshots," said the military source on condition of anonymity.
"When we heard of the ambush ... we mobilised our men to go to the scene but unfortunately we saw four people already dead," said Adamu Mamman, a civilian from the grassroots community security group JTF confirming the deaths.
Borno is the birthplace of Boko Haram, which has killed more than 600 people in a series of raids and bombings since President Muhammadu Buhari was sworn into office on May 29, after defeating incumbent president Goodluck Jonathan in elections upon campaigning on his determination to defeat Boko Haram, marking the first ever democratic shift of power in the country’s history.
Boko Haram has been fighting a six-year insurgency in a bid to establish a state of its own in northern Nigeria and killed thousands of people and displacing about 1.5 million in the process.
The group pledged its allegiance to ISIS in March.
