Pompeo faces opposition in UN push on Iran arms embargoUS Secretary of State Mike Pompeo on Tuesday urged the UN Security Council to extend an arms embargo on Iran, warning that the Middle East's stability was at risk, but he faced wide skepticism over US threats to trigger sanctions. The United States is adamant about prolonging the ban on conventional arms sales to its adversary which expires in October and has threatened to use a disputed legal move to force a return of UN sanctions on Iran.
