Nigeria’s president, Muhammadu Buhari has ordered for an investigation into the murder of a military couple.
The couple was killed over the weekend while heading to Imo state for their traditional wedding.
Reports say the attackers made a video of the incident and circulated it online.
Buhari said he was shocked to learn that a military officer and his female partner were shot dead and then beheaded in the south-east of the country.
The Nigerian military has described as despicable, the gruesome murder of an army couple just days to their marriage ceremony.
The president has ordered that the perpetrators of the barbaric crime be brought to justice.
Nigeria’s military has linked the beheading of the couple to the Indigenous People of Biafra (Ipob), a group that wants a breakaway state in south-east Nigeria.
The separatist group has denied their involvement.
Army spokesman Onyema Nwachukwu has blamed the armed wing of Ipob – the Eastern Security Network – for the killings.
“The Nigerian army will ensure the perpetrators of this dastardly act unleashed on its personnel do not go unpunished,” he said in a statement.
Ipob has not responded to the accusations by the army. The Ipob movement was founded by Nnamdi Kanu in 2014.
It wants a group of states in south-east Nigeria, made up mainly of people from the Igbo ethnic group, to break away and form the independent nation of Biafra.
