The leader of the jihadist group Boko Haram resurfaced in a video that was posted to social media on Sunday.
"You broadcast the news and published it in the social media that you injured or killed me, and here I am," the man said in the 40-minute video, according to Voice of America.
On YouTube, the video is dated Sept. 25.
BREAKING NEWS: NIGERIAN AIR FORCE RAID KILLS BOKO HARAM TERRORISTS COMMANDERS... “ABUBAKAR SHEKAU” FATALLY WOUNDED!— Nigerian Army (@HQNigerianArmy) August 23, 2016
In the video, the man claiming to be Shekau taunts the parents of the nearly 300 girls who were kidnapped from a Nigerian boarding school in 2014.
He teases parents about whether their daughters will be released and insists that Boko Haram fighters must be released first.
The kidnapping sparked global outrage and prompted global figures to support the #BringBackOurGirls campaign.
Some of the kidnapped teenagers were "given" to the terrorists as wives, according to CNN.
The Nigerian army dismissed the video and said it was just further proof of Shekau's desperation.
"The video has shown beyond all reasonable doubt the earlier suspicion that the purported factional terrorists group leader is mentally sick and unstable," the Nigerian army said in a statement. "The ranting is also another sign that the end is near for him which is part of the signs of all wicked people. The Nigerian Army wishes to assure the public that they should not be bothered by the contents of the video clip."
The army also said that Boko Haram has been significantly weakened.
