Iran has suspended uranium enrichment and all related activities, state-run radio reported Monday, honoring an agreement with Europe designed to head off possible U.N. sanctions. "To build confidence and in line with implementing the Paris Agreement, Iran suspended uranium enrichment (and related activities) as of today," said the brief radio announcement. In Vienna, the head of the U.N. nuclear watchdog agency said the suspension appeared confirmed. "I think pretty much everything has come to a halt," Mohamed ElBaradei, the head of the International Atomic Energy Agency, told reporters.
