A Chadian Air Force Su-25 (NATO: Frogfoot) aircraft accidentally fired a missile at Base Aérienne Kossei in Ndjamena, Chad.
The missile narrowly missed a French Air Force C-130H which is attached to the Transport Squadron 2/61 Franche Comté.
It subsequently struck the house of the Deputy Commander of the Presidential Guard, General Mahamata Salaha Brahima, causing four deaths and two injuries.
The cause of the incident is under investigation.
The Russia-made Su-25 is a twin R-195 engine ground attack aircraft with a maximum range of 1,000km and a top speed of 512kt. The aircraft is also in use by other African militaries including in Angola, DRC, Ivory Coast, Ethiopia and neighbouring Niger.
