A Chadian military tank inside Nigeria

The Chadian military, which recently regained from Boko Haram control of the Nigerian town of Gamboru, on the border with Cameroon, on Tuesday evening said they had pushed further into Borno state.

Two Chadian soldiers and several Boko Haram fighters were killed in violent clashes around Dikwa, some 50 kilometres (31 miles) southwest of Gamboru, on Tuesday afternoon.

A militant camp, which is near the group’s stronghold in the Sambisa Forest, was overrun, Chadian military sources said.

Chad’s presence well inside Nigerian territory is a first and may indicate a strategy to push on further to rebel-controlled areas to assist the beleaguered Nigerian military.
