Five people were killed during three suspected Boko Haram attacks in an overnight raid in Niger, security sources announced on Wednesday.
The Boko Haram militants are generally located in northeastern Nigeria but have threatened regional security with their ongoing attacks in the Lake Chad zone where there are the borders of Chad, Niger, Nigeria and Cameroon.
In the most deadly of the three attacks in less than 24 hours, militants killed two soldiers and three civilians in the town of Abadam which is on the western coast of Lake Chad.
About 150 km (90 miles) east in Chad, three militants were killed when they exploded suicide bombs after a number of local people found them.
"They were intercepted by villagers who wanted to search them and they resisted," said an unnamed local official.
In Cameroon's Far North Region, several alleged Boko Haram militants organised attacks on three food vehicles around the Chadian border on Wednesday and nobody died or got injured, officials stated.
Chad and Niger have been declaring a state of emergency for Lake Chad and Diffa continuously which have been targeted by several attacks within this year.
Since 2009, Boko Haram has killed at least 17,000 people, mostly in Nigeria, and displaced 2 million others.
Boko Haram was established in 2002. Since then, they have been carrying out their operations in West African countries including Chad, Niger and Cameroon.
The group's name translates to “Western education is forbidden" in the Hausa language that underlines the group's focus of opposing Western-style education.
