A video released by the Nigerian terrorist group Boko Haram purports to show its leader, Abubakar Shekau, pledging allegiance to the Islamic State.
Nigerian militant group Boko Haram has pledged allegiance to Islamic State (IS), according to an audio statement.
The message, which was not verified, was posted on Boko Haram’s Twitter account and appeared to be by the group’s leader, Abubakar Shekau.
Boko Haram began a military campaign to impose Islamic rule in northern Nigeria in 2009. The conflict has since spread to neighbouring states.
It would be the latest in a series of groups to swear allegiance to IS.
In the past Boko Haram is thought to have had links with al-Qaeda.
IS took control of large swathes of territory in eastern Syria and across northern and western Iraq last year.
The group aims to establish a “caliphate”, a state ruled by a single political and religious leader according to Islamic law, or Sharia. Its leader, Abu Bakr al-Baghdadi, is known to his followers as Caliph Ibrahim.
In the audio message posted on Saturday, the Boko Haram leader purportedly said: “We announce our allegiance to the Caliph… and will hear and obey in times of difficulty and prosperity.”
Boko Haram’s insurgency has threatened Nigeria’s territorial integrity and triggered a humanitarian crisis.
