Chad troops enter Nigerian town in pursuit of Boko Haram
Chadian troops clashed with Boko Haram fighters in the northeastern Nigerian town of Gambaru on Tuesday in a bid to break the Islamist insurgents' grip on the town bordering Cameroon, Chadian military sources said.
Chad has deployed some 2,500 troops as part of a regional effort to take on the militant group that has waged a bloody insurgency to create an Islamist emirate in northern Nigeria, which killed an estimated 10,000 people last year.
The fighting in Gambaru, south of Lake Chad, came as hundreds of Chadian soldiers massed near the town of Diffa in Niger, near Nigerian border northwest of the lake, military sources in Niger said.
