Three people died on Monday when a Nigerien military helicopter crashed on return from a routine training flight, the defence ministry said.
The accident happened when the Russian-built Mi-17 crashed as it was landing at a military base at Niamey airport.
“Unfortunately, all three crewmembers — a Nigerien officer and NCO and an expatriate instructor — died immediately despite efforts by rescue services to put out the fire,” it said in a statement.
An investigation has been launched, the statement said.
Niger, the world’s poorest country by the benchmark of the UN’s Human Development Index (HDI), has vowed to boost its military in the face of jihadist insurgencies in the southwest and southeast of the country.
