After American and British airstrikes late Thursday, a U.S. Navy vessel launched missiles at a Houthi radar facility in Yemen early Saturday.
Defense officials claimed Saturday's airstrike targeted a radar facility insurgents used to locate and attack Red Sea merchant ships. No location was given.
In response to monthslong Houthi attacks on commercial vessels, Thursday's attack hit around 60 military objectives in at least 28 places.
The two attacks increase U.S. engagement in Middle East warfare since the Israel-Hamas war began Oct. 7. Air and naval strikes targeted Houthi military locations.
The Houthis, an Iranian-backed Yemeni militia, attacked Red Sea commercial cargo immediately after Hamas entered Israel. Houthi commanders claimed the assault supported Hamas.
ABC News said that they targeted ships destined for Israel, although few had direct ties to Israel.
According to U.S. Central Command, militants have attacked 27 ships in international maritime routes using drones and missiles since Oct. 17.
"These strikes respond to unprecedented Houthi attacks on international vessels in the Red Sea, including the first use of anti-ship ballistic missiles," President Joe Biden stated late Thursday.
