"The U.S. and Britain have been intimately involved in prosecuting the war, supplying weapons, logistical help and diplomatic support to their longtime regional ally Saudi Arabia and its coalition, which also includes the United Arab Emirates, Bahrain, Kuwait, Jordan and Sudan. Besides selling weapons to the Saudis, American and British military advisers have provided training and intelligence and the U.S. has helped refuel coalition jets. Saudi airstrikes have repeatedly hit civilian targets — indiscriminate attacks that rights groups say are war crimes — despite sophisticated weaponry and Western intelligence."
