The United States is shifting military resources, including ships, in the Middle East in response to Israel's strikes on Iran and a possible retaliatory attack by Tehran, two U.S. officials said Friday.

The Navy has directed the destroyer USS Thomas Hudner, which is capable of defending against ballistic missiles, to begin sailing from the western Mediterranean Sea toward the eastern Mediterranean and has directed a second destroyer to begin moving forward so it can be available if requested by the White House.
