Kidnappers in Nigeria killed a British woman, a Nigerian man and abducted three others in Kaduna, local police and the British High Commission said.
Kidnappings are rampant in Nigeria, with locals and foreigners targeted — mostly for ransom.
The woman travelled from Lagos as a tourist and was attending a party before the incident, police said.
The British High Commission named the woman as Faye Mooney and said it was aware of the incident on Friday but would not speculate on the motive or nature of attack.
There has been no claim of responsibility for the incident and the kidnappers have yet to be identified, police said.
Mooney was employed in Nigeria by a non-governmental organisation called Mercy Corps. Her next of kin have been notified, the High Commission said.
“Suspected kidnappers armed with dangerous weapons gained entry to a recreational resort Kajuru Castle in Kajuru local government area shooting sporadically. In the process they shot dead two people, including an expatriate woman and took away three others,” Kaduna state police spokesman said.
The police did not name the other person killed.
Northern Nigeria is plagued by a Boko Haram and Islamic State insurgency as well as clashes between farmers and herders in which hundreds have died.
“We are engaging with the Nigerian authorities and we understand an investigation is underway,” the High Commission said in a statement.
President Muhammadu Buhari won re-election for four years in February, pledging to improve security in Nigeria, boost economic growth and fight corruption.
