> Meanwhile, aid agencies say the embargo imposed by the U.S. (and UK-backed) Arab coalition has had dramatic effect with about 80% of population in urgent need of vital resources such as food, water and medical supplies. Saudi Arabia, reportedly relying on U.S. intelligence reports and surveillance images for target selection, began airstrikes, some of which were against weapons and aircraft. The U.S. has dispatched warships in the region after Houthi missiles targeted the UAE-operated HSV-2 Swift, which some critics interpreted as the U.S. reinforcing the coalition blockade. According to Iranian sources, it has refueled Saudi planes, sent the Saudi military targeting intelligence, and resupplied them with tens of billions of dollars worth of bombs. The U.S. (and the UK) support the effort through arms sales and technical assistance. Amnesty International urged the U.S. and the UK to stop supplying arms to Saudi Arabia and to the Saudi-led coalition. It has been reported that U.S. is regarded as an indirect partner for Saudi Arabia in the war and blockade on Yemen.
