Jihadist group Boko Haram has replaced its leader, according to Chad President Idriss Derby. President Derby said the group is now headed by Mahamat Daoud, though he did not explain what happened to the previous leader, Abubakar Shekau.
Shekau frequently appeared in Boko Haram videos, though not recently. Some believe that he has been killed.
The BBC says that Derby is trying to come to a peace agreement with Boko Haram.
