Egypt ? The U.S. military has video and audio recordings of Iranian boats that threatened to blow up U.S. Navy vessels in the Strait of Hormuz and plans to release them, the top Navy commander in the Mideast said Tuesday. President Bush described the confrontation as a “provocative act.”

Vice Adm. Kevin Cosgriff disputed Iranian claims that the incident early Sunday was a routine encounter, saying Iran’s “provocative” actions were “deadly serious” to the U.S. military.

“It was a dangerous situation,” Bush told reporters at the White House. “They should not have done it, pure and simple. I don’t know what their thinking was, but I’m telling you what my thinking was. I think it was a provocative act.”

The confrontation was an unusual flare-up of U.S.-Iranian tensions in the Persian Gulf as Bush begins his first visit to the Mideast. In the tour, Bush is to visit Saudi Arabia and other Gulf Arab allies, in part to coordinate in confronting Iran.
