The U.N. nuclear watchdog has struck a deal with Iran to continue “necessary” verification and monitoring activities in Iran after Tehran slashes cooperation this week but there will be less access and no more snap inspections, its chief said. “What we agreed is something that is viable, it’s useful to bridge this gap that we are having, salvages the situation now,” Rafael Grossi told a news conference on Sunday after returning from a trip to Tehran for talks with Iranian officials on how his agency will carry out its work given Iran’s plan to scale back its cooperation with it as of Feb. 23.
