The United Nations Security Council is set to discuss on Monday a resolution to call out Iran over its weapons falling into the hands of Yemens Houthi insurgents. But Russia has laid the groundwork for a likely veto. The 15-member Security Council has to renew its targeted sanctions on Yemen on Monday. The United States has been lobbying for months for Iran to be held accountable at the United Nations, while at the same time threatening to quit a 2015 deal among world powers to curb Irans nuclear program if "disastrous flaws" are not fixed. Britain drafted a resolution in consultation with the United States and France that initially wanted to condemn Iran for violating an arms embargo on Houthi leaders and include a council commitment to take action over it. The latest British draft drops the condemnation and instead expresses concern that UN experts monitoring the sanctions reported Iran had violated a targeted arms embargo by failing to stop missiles and unmanned aerial vehicles reaching the Houthis. A UN Security Council resolution needs nine votes in favor and no vetoes by Russia, China, the United States, France or Britain to pass. Russia has proposed a rival resolution that would simply extend the mandate of the sanctions regime for one year and not mention Iran. Both resolutions seek to renew a UN ban on the supply of weapons to Houthi leaders and "those acting on their behalf or at their direction." It can also blacklist individuals and entities for threatening the peace and stability of Yemen or hindering aid access.
