US Ambassador Nikki Haley reiterated on Thursday that it was "time for the Security Council to act" following the release of a report by UN experts concluding that Iran had violated the arms embargo on Yemen. The report found that Tehran had failed to block supplies to Yemen's Houthi insurgents of ballistic missiles. "This report highlights what we've been saying for months: Iran has been illegally transferring weapons in violation of multiple Security Council resolutions," Haley said in a statement.
