Chad is mourning the death of four of its soldiers and treating a dozen others wounded in a mine attack at Kaiga Kindji near the border of Chad and Niger on Friday, August 26, 2016.

Mail Online quoted a security source who requested for anonymity as explaining that, "An army car hit a mine planted by Boko Haram at Kaiga Kindji, near the border of Chad and Niger.

There were four dead and a dozen wounded." The source added that the wounded soldiers were evacuated to the Chadian capital, N’Djamena. Reports say the attack was the latest in a series of attacks on Chadian soldiers by Boko Haram militants.

Boko Haram militants are making faint efforts through suicide bomb and mine attacks faced with the heavy artillery of joint task force made up of troops from Nigeria, Niger, Chad, Cameroon and Benin.

The task force has made significant gains in recent months against Boko Haram, driving them out of some of the group's Nigerian heartlands.

Reports say Boko Haram has continued to carry out suicide bombings and has retrenched to difficult-to-access areas such as the islands of Lake Chad and the Sambisa Forest near the border between Cameroon and Nigeria.
