Boko Haram leader Abubakar Shekau has threatened Cameroon in a message on the video-sharing site YouTube, warning that the same fate would befall the country as neighbouring Nigeria.
The video, which was posted on January 5, is directly addressed to Cameroon's President Paul Biya after repeated fighting between militants and troops in the country's far north.
"Oh Paul Biya, if you don't stop this, your evil plot, you will taste what has befallen Nigeria... Your troops cannot do anything to us," Shekau said in Arabic.
