US says if no arms embargo on Iran it will seek UN sanctions

U.S. Secretary of State Mike Pompeo threatened to seek to reimpose U.N. sanctions on Iran if the U.N. Security Council does not approve a resolution that would indefinitely extend the arms embargo on Tehran, which is set to expire in October. Tensions between Iran and the U.S. have escalated since the Trump administration withdrew from the 2015 nuclear deal between Tehran and six major powers in 2018 and reimposed crippling U.S. sanctions.
