Niger: Boko Haram rejected claims from Nigeria`s military that it has been routed by a four-nation offensive in a video released online on Tuesday, which does not show the group`s leader, Abubakar Shekau.
The unidentified speaker calls Nigeria, Cameroon, Chad and Niger, who have been battling the Islamists, "the lying coalition partners".
"Most of our territory is still under our control," said the speaker, whose face is not shown in the 10-minute message posted on YouTube.
The video bears the logo "Islamic State in West Africa" and follows the Nigerian militants` pledge of allegiance in March to the IS group, that has overrun large parts of Syria and Iraq.
The message is the first video released by Boko Haram since February, when Shekau was shown in high definition footage and vowed to disrupt Nigeria`s elections.
He had featured prominently in most of the group`s videos over the last three years and his absence in the latest message will likely stir further debate on his whereabouts or possible death.
Nigeria`s military has previously claimed to have killed Shekau and described him as a composite character, with the role of "Shekau" filled by various similar-looking insurgents at different times.
The speaker in the new message appears in front of two pick-up trucks, with four other gunmen visible in the background.
He speaks in the Hausa language that is dominant in northern Nigeria with Arabic and English subtitles shown below.
An AK-47 rifle rests on his chest as he seeks to rebuke the claims of successes made in recent weeks by the coalition.
"The armies claim through the media that they captured our towns and that they assaulted Sambisa (forest) and defeated us," he said, referring to the bushland area in Nigeria`s northeast Borno state that has been an Islamist stronghold.
"I swear by Allah that I am talking right now from Sambisa... Here in Sambisa you can travel more than four to five hours under the black flag of Islam by car or by motorbike," he added.
The latter parts of the video include depictions of gruesome violence, including executions of apparent civilians and one man in a Nigeria police uniform, who are shot at close range.
"President of Nigeria Jonathan" is mentioned, referring to Goodluck Jonathan, who handed over power to Muhammadu Buhari on Friday, two months after the latter`s victory in elections on March 28.
In his inaugural speech as president on Friday, Buhari described Boko Haram as "mindless" and "godless" and vowed to demolish the group during his tenure.
