Kabul: An Afghan official says a civilian helicopter has crashed in southern Afghanistan, killing all three people on board.

Marjan Haqmal, police chief of Nad Ali district in Helmand province, says the Russian-made aircraft probably went down because of a technical malfunction.

NATO confirmed that a civilian helicopter crashed in southern Afghanistan on Monday. It said the site of the crash has been secured and that coalition forces are trying to gather more information about what happened.

NATO did not provide information about casualties.

Dozens of Russian-built cargo helicopters are used by contractors working for the NATO-led coalition.

The coalition relies heavily on helicopters to avoid using roads that are frequently mined by the insurgents.
