strikes on Iran that killed the country's supreme leader and other top officials.

Iran insists it's not targeting countries in the region, but that it's defending against U.S.

strikes by targeting U.S.

troops at bases in the Gulf.

The U.S.

military says three U.S.

ground troops were killed and five seriously wounded as part of a support group in Kuwait.

But attacks have gone beyond just military bases in the Gulf.

Commercial ports in Dubai and Oman have been targeted, as have airports in Kuwait and the UAE cities of Abu Dhabi and Dubai, shutting down airspace and leaving thousands of tourists stranded.

High-rise towers and fancy hotels have also been struck by drones or fallen debris from missile interceptions in Bahrain and Dubai, including on its luxury Palm Island.

As of now, Gulf Arab states have not responded militarily to Iran's attacks.
