The strikes were aimed at al Qaeda in the Arabian Peninsula, and were the first such strikes to take place under President Donald Trump.
The strikes, which were later confirmed by the Pentagon, did not require Trump to sign off on them. Under then-President Barack Obama, the authority to order such strikes in Yemen was devolved to the four-star commander of US Central Command, Gen. Joseph Votel.
The strikes killed five al Qaeda operatives and took place in the town of al Bayda, according to Pentagon spokesman US Navy Capt. Jeff Davis.
Yemen is currently beset by a civil war between Houthi rebels, a minority Shia group from the north of the country, and the internationally recognized government, led by President Abdu Rabbu Mansour Hadi. Saudi Arabia is leading a military intervention against the Houthis in support of the government.
