IAEA Chief in Iran for Talks Before Showdown with West

DUBAI, UNITED ARAB EMIRATES - U.N. nuclear watchdog chief Rafael Grossi is set for talks in Iran on Sunday that may ease a standoff between Tehran and the West just as it threatens to escalate and scupper negotiations on reviving the Iran nuclear deal.

Grossi arrived in Tehran overnight, Iranian state media said, ahead of next week's meeting of the Board of Governors of the International Atomic Energy Agency. The IAEA and Iran's envoy to the agency said he would meet the new head of the Atomic Energy Organization of Iran, Mohammad Eslami. Grossi is expected to hold a news conference at Vienna airport around 8:30 p.m. (1830 GMT) after returning later on Sunday, the IAEA said. The IAEA informed member states this week that there had been no progress on two central issues: explaining uranium traces found at several old, undeclared sites and getting urgent access to some monitoring equipment so the agency can continue to keep track of parts of Iran's nuclear program as provided for by the 2015 deal.
