The more than a dozen strikes in Sana'a and other parts of Yemen are the first major ones since the Navy shot down its own F/A-18F.

The Houthi rebels are an Islamic political and military organization active in Yemen. The Houthis emerged in the 1990s when they rebelled against ruling regime in Yemen and were supported by Iran.

The head of the World Health Organization said he was about to board a flight in the Yemeni capital when the airport came under bombardment.

On Dec. 30 and 31, U.S. Navy ships and aircraft targeted a Houthi command and control facility and advanced conventional weapon (ACW) production and storage facilities that included missiles and uncrewed aerial vehicles (UAV). (U.S. Central Command Public Affairs)

The targets struck by U.S. forces had been used to attack American warships and commercial vessels, officials said.
