BOKO Haram, the insurgent group that has held Nigeria by the jugular has denied any suggestions that it would surrender, according to new video released Friday.

Recently, their shadowy leader Abubakar Shekau appeared in a rare message looking dejected and frail. Shekau, who has not been seen on camera for more than a year, re­leased an unverified video last week and said his time in charge of the Ni­gerian jihadist group may be coming to an end. If the video indeed depicts Shekau, he appears thin and listless, delivering his message without his trademark fiery rhetoric.

It prompted speculation from the army that the Islamist group was on the verge of collapse in the face of a sustained military counter-insur­gency.

However, in Friday’s message, Boko Haram maintained it was a potent fighting force, with fighters posing with AK-47s in front of Toy­ota Hilux pick-up trucks and a lorry mounted with a military cannon.

“You should know that there is no truce, there is no negotiations, there is no surrender,” an unidentified masked man wearing camouflage said in a prepared script in Hausa, in the video posted on YouTube.

“This war between us will not stop.” The video, which was of markedly better quality than Shek­au’s and included Arabic subtitles, featured nine masked Boko Haram fighters standing on sandy ground in an undisclosed desert location. It is unclear if the masked people in the video include the Boko Haram leader.

Shekau was still the head of the “West African wing”, said the masked man in the video, likening Boko Haram to the Islamist insur­gencies in Iraq, Libya and Syria.

In March 2015, Boko Haram pledged allegiance to the Islamic State group, another of the world’s most deadly terror organisations. But there were few signs Boko Ha­ram — now styled as Islamic State in West Africa Province (ISWAP) — has so far benefited from the partnership. Nigeria’s army has since then won back swathes of ter­ritory from the militants, liberating thousands living under Boko Haram control.
