Saudi Arabia and its Gulf allies have presented powerful members of the U.N. Security Council with suggested elements for a resolution that would impose an arms embargo on the Shiite rebels who have thrown Yemen into turmoil and caused its Western-backed president to flee.

Diplomats said Thursday after a meeting with ambassadors from the United States, Britain and France that members of the Gulf Coordination Council want the resolution to be militarily enforceable under Chapter 7 of the U.N. Charter.

The GCC members also presented the Security Council president with a letter explaining that their airstrikes targeting military installations held by the Houthi rebels are in response to President Abed Rabbo Mansour Hadi's request this week for immediate aid as the rebels closed in.
