Chad's army said it had killed more than 200 militants from
Boko Haram on Tuesday in a battle in the northeastern Nigerian towns of Gambaru
and Ngala, which are near the border with Cameroon.
Chad has deployed 2,500 troops as part of a regional effort
to take on the militant group, which has been fighting for five years to create
an Islamist emirate in northern Nigeria. An estimated 10,000 people died in the
region last year.
