TEHRAN (AP) — Talks between Iran and the International Atomic Energy Agency will be “technical” and “complicated,” the Islamic Republic’s Foreign Ministry said Monday ahead of a visit by the nuclear watchdog for the first time since Tehran cut ties with the organization last month.

A senior official from the United Nations’ nuclear watchdog will fly to Iran for talks on Monday, but no visit to nuclear sites is planned, Iran’s Foreign Minister Abbas Araghchi said on Sunday.

Iran has had limited IAEA inspections in the past as a pressure tactic in negotiating with the West, and it is unclear how soon talks between Tehran and Washington for a deal over its nuclear program will resume.
