support to the Saudis and their allies, particularly the United Arab Emirates. According to this report, the US role in Yemen war moves beyond supplying training and intelligence support and sales billions of dollars of weaponry to UAE and Saudi Arabia, America's largest weapons buyers. United Kingdom's role Although Britain has called on Saudi Arabia to ease the siege on Yemen and the British government allocated 4 million pounds to aid meet emergency requirements, the UK government has officially supported the Saudi-led coalition since the beginning of the conflict.
