A Nigerian diplomat was found dead in his home in the Sudanese capital Khartoum on Thursday, Reuters reported, citing two security sources. They said police were investigating the incident, providing no details on how he died. The Nigerian Embassy in Khartoum has not commented on the report. Al-Arabiya television identified the diplomat as the consul-general and described his death as an “assassination.” Though intermittent violence is common in the warring southern and western regions, violence in the capital is rare. Sudan’s President Omar Hassan al-Bashir replaced the heads of the army and intelligence service in February.
