The governor of Kaduna state in Nigeria has been killed in a helicopter crash in the southern delta region.
The BBC reports Governor Patrick Ibrahim Yakowa and former national security adviser Gen Owoye Azazi were on the helicopter which came down in Bayelsa state at about 3.30pm on Saturday.
Nigerian media said the helicopter belonged to the Nigerian navy and was en route to Port Harcourt.
Analysts say Nigeria has a poor air safety record. In March a police helicopter carrying a high-ranking police official crashed in the city of Jos, killing four people.
