US submarine attack on Iranian warship examined by legal experts. International law specialists say the torpedo strike on IRIS Dena in the Indian Ocean does not appear to violate international or American military law. The vessel was confirmed as a legitimate military target, though eighty-seven personnel died in the incident. Legal experts note that targeting military vessels during operations is not considered a war crime under international law. However, questions remain regarding rescue efforts for the thirty-two survivors recovered after the attack. The broader US-Israeli military operation against Iran continues to face scrutiny regarding its alignment with UN charter provisions and international legal frameworks.
