Seven Chadian soldiers and a local guard were killed in a Boko Haram jihadist ambush in Lake Chad, the latest in a surge of attacks in the region, security sources said on Sunday.
Boko Haram militants have been waging a decade-long insurgency in northeast Nigeria, but the conflict has spilled into Lake Chad where Nigeria borders Niger, Chad and Cameroon.
Security sources said the seven Chadian soldiers and the guard were killed in an ambush on Friday in Mbomouga in Chad’s Ngouboua area, and another 13 people were wounded.
“The Boko Haram forces lost six of their people and left behind two weapons,” one security source said.
Among the soldiers killed was a gendarme colonel, the source said. Another source said three army officers were killed in the attack.
Since 2018, Boko Haram has carried out at least nine attacks on Chad. But the jihadist group has stepped up attacks outside Nigeria after a period of calm last year.
Last month, militants killed four people in an attack on a Cameroonian island on Lake Chad and Boko Haram killed another 13 villagers in eastern Chad.
In March jihadists killed at least 23 Chadian soldiers in an attack on an army post in the group’s deadliest attack on the country’s military.
Since 2015, troops from Cameroon, Chad, Niger and Nigeria have been grouped into a mixed, multi-national force in a bid to help fight Islamist militants.
