Militant Islamists have released a new video on the insurgency in Nigeria, with Boko Haram leader Abubakar Shekau again failing to appear in it.
His continued absence has increased speculation about his fate.
He was last heard from in March, when he released an audio message pledging allegiance to the Islamic State (IS) group.
Soon thereafter, Nigeria’s military said it had recaptured all towns and cities from Boko Haram.
The military said on Sunday that it had freed 178 people held captive by Boko Haram in north-eastern Borno state.
It had also killed militants and captured a commander following airstrikes on the group’s bases, it added.
The video shows the militants attacking a security checkpoint, seizing weapons, and slitting the throat of a man dressed in a police uniform.
Mr Shekau also failed to appear in a Boko Haram video released in June.
