An Afghan Mi-17 military helicopter crashed on Sunday after a technical failure during a training exercise, killing three air crew and wounding another in Logar province, south of the capital Kabul, the Defence Ministry said, according to Reuters.

The Mi-17, a transport and attack helicopter, is the mainstay of the fledgling Afghan air force, which has around 50 of the Russian-made machines. Another 36 are used by Afghan special forces.
