N'DJAMENA, March 4 (Reuters) -
President Idriss Deby of Chad said on
Wednesday he knew the whereabouts of
Nigerian Boko Haram militant leader
Abubakar Shekau and called on him to
surrender or face being killed.
Chad's army has waged a series of
battles against Boko Haram as part of a
cross-border military campaign and has
retaken territory the militant group held in
northeastern Nigeria.
