Embattled Boko Haram leader Shekau shows up again looking healthy in new video

The embattled leader of jihadist group Boko Haram, Abubakar Shekau, resurfaced in a video posted online Sunday, rejecting assertions by the Nigerian army that he had been seriously wounded.

"You have been spreading in the social media that you injured or killed me," Shekau said in the 40-minute video released on YouTube and dated September 25.

"Oh tyrants, I'm in a happy state, in good health and in safety."

The Nigerian army said on August 23 that Shekau had been seriously wounded in the shoulder in an air raid in which several commanders were killed.

The army's claim was bolstered when Boko Haram released a video on September 13 without Shekau in it.

That video, also posted on YouTube, shows an unidentified man who says he is representing Shekau, who had allegedly been ousted by the Islamic State group to which Boko Haram pledged allegiance in March 2015.
