Nigeria’s top-ranking army commander Lieutenant General Ibrahim Attahiru died when his plane crashed in the country’s northern state of Kaduna Friday, according to Nigerian military officials.

The cause of the plane crash was blamed on “inclement weather” as the plane was landing at the Kaduna International Airport, the armed forces said in a statement adding that the crash “claimed the lives of 10 other officers including the crew.” The names of the other officers were not released.

Army spokesman Brigadier General Mohammed Yerima said more details of the crash would be released soon.

This is the third air crash by Nigerian aircraft this year. 

Attahiru was reportedly visiting the restive Kaduna state. He’d only been appointed to the position in January.

His appointment was part of a large army shake-up to deal with the decade-long Boko Haram insurgency which has placed Nigerian President Muhammadu Buhari under political pressure.

Buhari, in a released statement on Twitter, described the crash as a “mortal blow to our underbelly at a time our armed forces are poised to end the security challenges facing the country.”
