The military says the arrest of a Nigerian terrorist leader in neighboring Niger has foiled a plot to regroup and launch more attacks.

A statement from Nigeria's military Wednesday says intelligence agents from both countries had been on the trail of the leader who was arrested Saturday in a border area. It does not identify the leader or his group.

Northeast Nigeria bordering Niger and Chad is in the grips of an Islamic extremist uprising that forced the government to declare a state of emergency in May and flood the area with troops. Hundreds of kilometers of porous borders are patrolled by soldiers from all three nations.

The statement said the arrested leader had fled the clampdown and was recruiting and training militants in Niger for terrorist attacks in Nigeria.
