A draft resolution proposed by the United States, France, the United Kingdom, and Germany for next week’s meeting of the United Nations nuclear watchdog’s Board of Governors calls on Iran to respond to the watchdog’s long-standing queries about uranium traces discovered at three locations.

The International Atomic Energy Agency’s 35-nation Board “urges Iran to act immediately to fulfill its legal obligations and accept the (IAEA) Director General’s offer of further engagement to clarify and resolve all outstanding safeguards issues,” according to a draft text sent to IAEA member states and obtained by Reuters on Wednesday.
