A Nigerian diplomat was found dead on Thursday at his home in the Sudanese capital, Khartoum, the News Agency of Nigeria has reported, quoting two security sources.
According to the report, the sources said police were investigating the incident but provided no details on how he died.
Reuters that initially reported the incident said officials from the Nigerian Embassy in Khartoum were not immediately available to comment.
Dubai-based al-Arabiya television identified the diplomat as the consul general and described his death as an “assassination”.
Reports on social media suggested the killers used a knife in the attack.
Though intermittent violence is common in the country’s warring southern and western regions, violence in the capital is rare.
Sudan’s President Omar al-Bashir has in recent months shaken up the security establishment, replacing the heads of the army and intelligence service in February.
They said he had apparently been killed and that an investigation was underway.
Reacting to the news, the Ministry of Foreign Affairs said it was awaiting a detailed report on the killing.
The ministry spokesman, Tope Elias-Fatile, in a statement in Abuja on Thursday, expressed sadness over the incident.
“The ministry has received the sad news of the untimely death of the immigration attaché in our Mission in Khartoum, Sudan.
“We are awaiting further/detailed report from the Mission after which a statement would be issued,” said Elias-Fatile.
The statement did not also provide the name of the victim.
