WASHINGTON, May 19 (Reuters) - A U.S. military investigation into a strike at a girls' school in Iran has been "complex" given that it was located on an active Iranian cruise missile base but the probe is approaching its conclusion, a U.S. military commander said on Tuesday.
Reuters first reported that an initial, internal U.S. military investigation showed U.S. forces were likely responsible for the fatal strike in Minab. The Pentagon has since elevated the probe but it has not acknowledged any preliminary findings.
