A British hostage, kidnapped in Nigeria has been killed, while three others have been released, according to a Sky news report.
Details surrounding the death of missionary Ian Squire, who was abducted on 13 October, were not immediately clear.
Fellow Christian charity workers Alanna Carson, David Donovan and Shirley Donovan have been released following negotiations.
During the course of their investigations into the death, Police in Nigeria believe militants operating in the area are responsible and have now have arrested four people.
The Foreign Office (FCO) said they were supporting the families of the three released Britons, who have now returned home.
The group, who had been providing “free medical care and religious activities” to the local Enukorowa community, are understood to have been held at militant camps in the creeks and swamps of the delta.
The community were said to be “saddened” by their kidnapping.
The state police said it was “unfortunate” the group had not informed them of their presence, despite living in the area for the past three years.
The families of Mr Squires and the other hostages said the kidnap had been “traumatic for all concerned”.
While the statement said they were “delighted and relieved” for the three freed hostage, they said “our thoughts are now with the family and friends of Ian as we come to terms with his sad death”.
