Iranian missile strikes continue in Israel.....

American air defense systems and Navy assets in the Middle East helped Israel shoot down incoming ballistic missiles Friday that Tehran launched in response to Israeli strikes on Iran's nuclear facilities and top military leaders, U.S. officials said.

The U.S. has both ground-based Patriot missile defense systems and Terminal High Altitude Air Defense systems in the region capable of intercepting ballistic missiles, which Iran fired in multiple barrages in retaliation for Israel's initial attack.

Naval assets also were involved in assisting Israel as Iran fired missiles at Tel Aviv, one official said. It was not immediately clear if ships fired interceptors or if their advanced missile tracking systems helped Israel identify incoming targets.

The United States also is shifting military resources, including ships, in the Middle East in response to the strikes.

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, U.S. officials said.

American fighter jets also are patrolling the sky in the Middle East to protect personnel and installations, and air bases in the region are taking additional security precautions, the officials said.
