Release site: The United Arab Emirates has been covertly providing aid and intelligence to Iran-backed Houthi rebels against Saudi forces, according to four Saudi forces. The arrangement, which includes direct intelligence sharing for Yemeni operations but not for attacks inside Saudi Arabia, continues despite a senior US official warning the UAE to end support. One of the Houthi attacks on Saudi Arabia's main airport killed 12 people, injured more than 300 and caused the cancellation of the Future Investment Initiative conference.
