The suspected leader of Nigerian Islamist extremist group Boko Haram has issued a threat in a YouTube video over a US-made anti-Islam film that has sparked widespread protests in the Muslim world.
"First, insults against the prophet, evil plots against him, making blasphemous movies against him, all these will do no harm to Islam," Abubakar Shekau says in the video which appears to have been posted on Sunday. "Anybody plotting this will surely pay for it. Everybody knows what this statement entails. Everybody should wait and see what we will do regarding this."
