Army investigating deaths of two Afghans

KABUL, Afghanistan -- U.S. Army criminal investigators were looking into the deaths of two Afghan prisoners at a U.S. detention facility in Afghanistan, the military said Tuesday.

The detainees died Dec. 3 and Dec. 10 at a makeshift prison in the U.S. military headquarters at Bagram Air Base, north of the capital, Kabul, the U.S. military said in a statement.

Autopsies performed by coalition medical teams -- which included representatives from Jordan, Korea and the United States -- found that the first inmate died of a pulmonary embolism and the second died of a heart attack.

"An investigation has been initiated by the Army's criminal investigation division to determine if the circumstances of their detention was related or contributed to their deaths," the statement said.

It's not clear how many inmates are being kept in the facility, but American and coalition troops hunting for al-Qaida and Taliban remnants regularly detain and interrogate suspects at Bagram.
