KANDAHAR, Afghanistan, Nov. 24 (Xinhua) -- At last two Afghan army personnel were killed and two others injured after a military helicopter made a crash landing in the country's southern province of Kandahar on Saturday, an army source said.

"The incident took place in Maruf district shortly after the Afghan Air Force helicopter took off from an army camp Saturday morning," the source told Xinhua anonymously.

The Taliban militant group has claimed that its fighters had shot down an army chopper in Kandahar. However, the source ruled out insurgents' activities at the area, saying the incident occurred due to technical failure in the province, 450 km south of Kabul.

Security situation has been improving in Kandahar, the former stronghold of Taliban, over the last months as security forces have conducted search and cordon operations across the province. But the militants attack government interests in the province from time to time.

Late last month, 21 people were killed after an Afghan army helicopter crashed in western Farah province.
