'Son' of Boko Haram's founder named jihadi head

When the Islamic State (IS) group appointed Abu Musab al-Barnawi as the head of Boko Haram early in August, few people even recognised his name.

But to close observers of Nigerian jihadi affairs, Barnawi's promotion from relatively unknown spokesman to leader came as no surprise.

After all, many experts say that Barnawi, born Habib Yusuf, is the 22-year-old son of Boko Haram's founder Mohammed Yusuf.

Barnawi's appointment by IS has deepened a rift with longtime chief Abubakar Shekau, who later released a video insisting he was in charge and vowing to fight on.

Nigeria's military claimed on Tuesday that Shekau had been wounded in an air strike on Boko Haram's forest stronghold but this has not been confirmed yet.

Yusuf senior died in police custody following a 2009 military crackdown on the sect in the northeastern city of Maiduguri that spurred the group to take up arms against the Nigerian government.

"Abu Musab al-Barnawi is the son of late Mohammed Yusuf," tweeted Ahmad Salkida, a Nigerian journalist who specialises in covering the insurgency.

"He is the first surviving son," confirmed Fulan Nasrullah, a conflict researcher based in Nigeria, also in a Twitter post.

Shekau himself had taken Barnawi under his wing when he was still a teenager, and gave him a new Arabic name meaning the man from Borno.

Barnawi was like a younger brother or son to Shekau, Nasrullah said, describing him as one of the chief's two trusted right hand men.

The teenager could not have had a more fearsome mentor.

Shekau instructed him in the art of war as he transformed Boko Haram from a strict Islamic sect into a jihadist movement that laid waste to swathes of territory in the northeast.

Since 2009, the group has killed an estimated 20,000 people, prompted 2.6 million to flee their homes, and kidnapped thousands of people, including hundreds of schoolgirls from Chibok in the northern state of Borno.

Barnawi made his first public appearance in a January 2015 video claiming responsibility for a Boko Haram attack in the northeastern town of Baga, where many civilians were massacred.

The first signs of a rift appeared after Shekau pledged allegiance to IS in March that year and changed Boko Haram's name to Islamic State West Africa Province.
