The United States and the United Kingdom defended their actions in front of the United Nations Security Council regarding the recent attack on Houthi rebels in Yemen. However, Russia and China expressed concerns, accusing the Western allies of escalating regional tensions. Other Security Council member states also condemned the US and UK attacks in Yemen. During a Friday debate, the Security Council discussed the US and UK strikes on Yemeni cities targeting Iran-backed Houthi rebels. US Ambassador Linda Thomas Greenfield asserted that the attack adhered to international law and the UN Charter. She emphasized that the operation aimed to diminish the Houthis' capacity to recklessly attack ships. The United States and the United Kingdom launched strikes against Houthi-held areas in Yemen in response to Houthi attacks on ships in the Red Sea. British Ambassador Susan Woodward stated, "We have taken necessary and reasonable measures in a limited form with the United States for the sake of self-defense." She mentioned that the Netherlands, Canada, Bahrain, and Australia supported the campaign, although they did not actively participate. Russia's Ambassador to the Security Council, Vasily Nebenzia, lodged a complaint, alleging that the US and the UK violated international law by attacking Yemen, thereby escalating regional tensions. Nebenzia emphasized the unacceptability of attacking commercial ships and distinguished between preventing such attacks and unjustly and indiscriminately attacking other states. Meanwhile, US President Joe Biden warned of additional military action against Yemen's Houthi rebels if they persist in attacking ships in the Red Sea. Biden issued this warning while addressing reporters in Pennsylvania. "If the Houthis continue to carry out such heinous acts, we will certainly respond," Biden stated. The Pentagon claimed that the US and UK strikes in Yemen successfully reduced the Houthis' ability to launch new attacks, targeting 60 locations in 28 locations. Having controlled much of Yemen for nearly a decade, the Houthis announced their intention to continue attacking territorial ships. Due to Houthi attacks, more than 2,000 ships have been diverted from the Red Sea since November.
