RIYADH: Saudi Arabia has welcomed the United Statess decision to return the Fordow nuclear facility in Iran to the sanctions list.  Washington said on Monday that it will no longer waive sanctions related to Iran’s Fordow nuclear plant after Tehran resumed uranium enrichment at the underground site.  “The right amount of uranium enrichment for the world’s largest state sponsor of terror is zero ... There is no legitimate reason for Iran to resume enrichment at this previously clandestine site,” US Secretary of State Mike Pompeo told reporters earlier this week.
