Two NATO occupation troops were killed on Wednesday as their helicopters crashed in eastern Afghanistan.

Taliban claimed the attack, saying its militants have shot down two helicopters in Logar province, just south of the capital Kabul.

However, NATO said the cause of the crash was under investigation.
"An ISAF helicopter has crashed in eastern Afghanistan, resulting in two ISAF fatalities. We are investigating the cause," a spokesman for NATO's US-led International Security Assistance Force told AFP.

The administration in Logar said the area is largely under Taliban control and 13 kilometres (eight miles) north of the provincial capital Puli Alam.

"There was a helicopter incident in Baboos area, which is an area largely under the Taliban control," said provincial spokesman Din Mohammad Darwish.
The area was "inaccessible" to Afghan forces, he added.
