A new visual analysis by The New York Times and munitions experts has uncovered additional evidence showing that the weapons that struck a sports hall, a school and two residential areas in the Iranian city of Lamerd were U.S.-made Precision Strike Missiles, or PrSMs. The U.S. military has rejected the conclusions of earlier investigations by The Times and other news organizations that found that PrSMs had hit civilian locations in Lamerd on Feb. 28.
