The Pentagon is expanding its military presence in the Middle East and Europe in response to worsening hostilities between Israel and Iran, U.S. officials said Monday, sending refueling planes and an additional aircraft carrier among the resources dispatched.

U.S. officials told multiple outlets that the Navy directed the USS Thomas Hudner, a destroyer capable of intercepting ballistic missiles, from the western Mediterranean Sea toward the eastern Mediterranean Sea, where it will join the USS Arleigh Burke. A second destroyer was also ordered to change course to be available if requested.
