The International Red Cross says it found between 400 and 600 bodies in the northern Afghan town of Mazar-e-Sharif after its recent capture by the Northern Alliance.
But an agency official could not say whether the dead had been executed or killed in fighting that preceded the fall of the town.
The Red Cross official said all she knows is that up to 600 bodies were found and 300 have been buried. She also could not link the dead to a specific ethnic group.
The Northern Alliance swept into Mazar-e-Sharif last week, seizing control from the Taleban in the first in a rapid series of victories across the country.
