PENTAGON HAS NO INFORMATION ON IRAN ATTACK RUMORS A U.S. Defense Department spokesman said he had no information on London oil and stock market rumors that the United States had launched a retaliatory strike against Iran for an attack on Friday that damaged a U.S. shi "I don't have anything," Major Randy Morger said. "I have no information at all." President Reagan said on Sunday he had already made a decision on the U.S. response to Friday's Iran attack but would not say what the decision was. Defense Secretary Caspar Weinberger said on Saturday the attack on a U.S.-flagged ship in Kuwaiti waters on Friday was almost certainly by an Iran Silkworm missile. Some of the rumors in the London markets were that the United States had launched an offshore strike against Iranian missile installations.
