(CNN) -- American airstrikes earlier this month during a western Afghanistan battle with Taliban militants may have killed up to 30 civilians, an interim U.S. military report said on Wednesday. Villagers sit near the graves of victims of airstrikes in Garni, in western Farah province. The report is part of an ongoing investigation into a fight in Farah province, where villagers reported civilian casualties as a result of U.S. bombing runs on May 4. "A review of the physical evidence is inconclusive in determining the exact number of civilian and insurgent casualties," the military said in a statement detailing the report.
