KABUL, Nov. 30 (Xinhua) -- An Afghan army general has been killed and several army personnel wounded after a helicopter crashed in western Badghis province, sources said.

"Brigadier General Muhayuddin Ghori, commander of Afghan National Army's 207th Zafar Corps based in western Herat province, was martyred after an ANA chopper crashed in Mori Chaq district, Badghis province late Tuesday," a military official told Xinhua anonymously Tuesday.

The province has been the scene of heavy clashes between security forces and Taliban militants over the past couple of months.

The source ruled out involvement of the insurgents in the incident, saying the crash was caused by a technical failure in the aircraft.

Further details about the incident are still forthcoming amid the absence of any official statement.

The Afghan security forces' casualties have risen recently as they struggle against a surge in attacks by Taliban militant group and other anti-government fighters.
