Kabul - A military helicopter crashed in a mountainous area in northern Afghanistan, but it was not known if there were casualties, local official said Thursday.

The helicopter crashed on the Hindu Kush mountains in northern Baghlan province on Thursday morning, Abdul Majeed, provincial intelligence chief said.

He said he did not know of the aircraft belonged to Afghan or international troops stationed in the country or if there were any casualties.

A Kabul-based spokesman for NATO-led forces said the organization's headquarters checked with all 42 nations that have troops in Afghanistan, but, "All our aircraft were accounted for."(dpa)
