Turkey's military says one of its helicopters has crashed into a house on the outskirts of the Afghan capital Kabul, killing 12 Turkish soldiers.

Authorities say the Sikorsky helicopter crashed into the house Friday in the Bagrami district.

The Turkish military said the aircraft belonged to the Turkish armed forces and was part of the NATO mission in Afghanistan.

The cause of the crash was not immediately clear.

In eastern Afghanistan, NATO says one of its service members died Thursday in a bomb blast.
