Officials with U.S. Central Command first disclosed details about the incident last month. Approximately 20 minutes before the incident occurred, the Iranians had announced over maritime radio that they would be carrying out a live-fire exercise, officials said. Although the rockets traveled away from the Truman, firing weapons "so close to passing coalition ships and commercial traffic within an internationally recognized maritime traffic lane is unsafe, unprofessional and inconsistent with international maritime law," said Cmdr. Kevin Stephens, a spokesman for the U.S. Navy's Fifth Fleet. Iran had dismissed the U.S. claim as "psychological warfare" against the Islamic Republic.
