The fighting was taking place as NATO began an operation to recover the remains of the large transport helicopter that was shot down by insurgents early Saturday in the Tangi Joy Zarin area of Wardak province's Sayd Abad district, about 60 miles (97 kilometers) southwest of Kabul.
The clashes today did not appear to involve the troops around the crash site.
"There have been a small number of limited engagements in the same district as yesterday's helicopter crash, however those clashes have not been in the direct vicinity of the crash site," NATO said in a statement. "As of now, we have no reporting to indicate any coalition casualties resulting from these engagements."
"There is a joint operation going on by Afghan and NATO forces. A clearing operation is ongoing in the district and there are reports of casualties among insurgents," Shahid said. "The area is still surrounded by American forces."
Elsewhere in Afghanistan, NATO said insurgents killed four alliance service members in two separate attacks in the east and the south. It did not provide their nationalities or any other details.
