A man purporting to be the leader of Nigerian militant sect Boko Haram has threatened to step up violence in neighbouring Cameroon unless it scraps its constitution and embraces Islam.
Only weekend, the group overran the headquarters of the multinational force in Baga, Borno state.
The video which was posted online shows a man who looks like the group’s head, Abubakar Shekau, being filmed from a distance at different angles.
The latest message is addressed to Cameroon President Paul Biya.
At least 15 people were killed in an attack by suspected Boko Haram militants on a bus in northern Cameroon on New Year’s day .
“I advise you to desist from following your constitution and democracy, which is unIslamic,” the man says, reading from a script.
“The only language of peace is to repent and follow Allah, but if you do not then we will communicate it to you through the language of violence,” he adds.
Boko Haram which has remained a security threat to the Nigerian Governmen has also become a growing menace to neighbours Cameroon, Chad and Niger.
