I'm Still Alive - Boko Haram Leader Abubakar Shekau

Abubakar Shekau says he is alive and still the leader of Islamist sect Boko Haram, denying reports he is dead, according to a new audio message quoted on social media on Sunday.

Social media feed of jihad monitoring site Site Intelligence quoted a new audio message released from Shekau denying reports that he is unable to serve as leader.

There have been several claims by Nigeria's military that Shekau has been killed over the last few years but he keeps resurfacing in new videos or it could be "impostors" posing with the same name, security sources have said.

Last week Chad's President Idriss Deby said Boko Haram leader Shekau was wounded and has been replaced as leader by Mahamoud Daoud, adding that Shekau went to Maiduguri, capital of Borno state, after he was wounded.
