About ten Chadian soldiers died in fighting to free two towns in northern Nigeria previously held by Boko Haram, the first gains against the militants made in a joint offensive launched with Niger at the weekend, military sources said on Monday.
President Idriss Deby of Chad said on Wednesday he knew the whereabouts of Abubakar Shekau, the leader of the Nigerian militant group Boko Haram, and called on him to surrender or risk being killed.
A black and white Boko Haram flag still flutters on top of a deserted villa in the Nigerian town of Dikwa, overlooking a courtyard filled with dirty mattresses and charred vehicles.
