(Adds comments from Buhari)
MAIDUGURI/CAIRO, Dec 27 (Reuters) - Islamic State released a
video purporting to show its militants beheading 10 Christian
men in Nigeria, saying it was part of a campaign to avenge the
deaths of its leader Abu Bakr al-Baghdadi and its spokesman.
The militant group posted the footage on its online Telegram
news channel on Thursday, the day after Christmas, with Arabic
captions but no audio.
The video showed men in beige uniforms and black masks
lining up behind blindfolded captives then beheading 10 of them
and shooting an 11th man.
An earlier video seen by Reuters said the captives had been
taken from Maiduguri and Damaturu in Nigeria's northeastern
state of Borno, where militants have been fighting for years to
set up a separate Islamist state.
In that video, the captives pleaded for the Christian
Association of Nigeria and President Muhammadu Buhari to save
them.
Reuters could not verify the authenticity of either video.
In a series of comments on Twitter, Buhari condemned the
killings.
"These agents of darkness are enemies of our common humanity
and they don't spare any victim, whether they are Muslims or
Christians, and therefore, we shouldn't let them divide us and
turn us against one another," Buhari wrote.
Islamic State in West Africa Province (ISWAP) split from the
militant group Boko Haram in 2016 and has become the region's
dominant jihadist group. Islamist insurgents have killed about
30,000 people in northern Nigeria in the past decade.
Islamic State leader Baghdadi died during a U.S. military
raid in Syria and Muhajir in a separate military operation, both
over the same weekend in late October.
