A Nigerian diplomat was found dead in his home in the Sudanese capital, two security sources said, in an apparent murder police said did not appear to be politically motivated.
Police spokesman Omar al-Mokhtar said the unidentified diplomat, who was working in the immigration section of the Nigerian Embassy, was stabbed to death and police had ruled out the possibility of a terrorist attack.
Mokhtar said several suspects were arrested, but provided no further details.
Officials from the Nigerian Embassy in Khartoum were not available to comment.
Dubai-based al-Arabiya television earlier described the diplomat’s death as an “assassination”.
Intermittent violence is common in Sudan’s ethnically torn southern and western regions, violence in the capital is rare.
President Omar Hassan al-Bashir recently shook up the security establishment, replacing the heads of the army and intelligence service.
