KABUL, Afghanistan. — An International Security Assistance Force CH-47 helicopter conducted a forced landing during a mission in southern Afghanistan Friday.

The helicopter was flying a troop transport mission with 12 passengers and five aircrew aboard. Shortly after landing, another ISAF helicopter arrived on the scene and transported the passengers to a nearby ISAF facility without further incident. No one aboard the helicopter was harmed.

A maintenance team conducted an initial assessment, and it appears that the forced landing was the result of a mechanical issue. No insurgent activity was reported during the landing. A complete assesment will be conducted to determine the nature of the forced landing.

The aircraft was repaired on site and flew back to its operating base late Friday evening
