The Afghan National Army's (ANA) Mi-17 military helicopter has crashed during a training exercise in Logar province, south of Kabul, killing three Afghan soldiers and wounding one.
The Afghan Ministry of Defence has not yet confirmed the reason for the incident. Media reports claim that the crash followed a technical failure.
In August last year, an Mi-17 aircraft crashed in Shinkay, Afghanistan, killing around 17 people.
The Taliban claimed responsibility, but the Afghan MoD rejected the claims, citing technical failures as the cause of the crash.
The country currently operates 86 Mi-17 aircraft, which were delivered as part of a contract signed between Russian state-arm exporter Rosoboronexport, and the US Department of Defense (DoD) in 2011.
The helicopters are intended to enhance the Afghan national security forces' capabilities for urban warfare and special units operations against Taliban insurgents.
Russia has delivered nine helicopters to Afghanistan, while the remaining helicopters are undergoing assembly and testing.
An export version of the Mi-8 Hip helicopter, the Mi-17 is equipped with two TV3-117BM turboshaft engines, ten large-calibre machine guns, four outboard cassettes with 20 unguided missiles, and night vision goggles (NVGs).
