A team of UN nuclear inspectors returned Thursday from a visit to a previously secret Iranian uranium enrichment site and their leader expressed satisfaction with the mission.
"We had a good trip," said Herman Nackaerts, who headed the International Atomic Energy Agency inspection team.
Nackaerts said the nuclear agency planned to analyze the data from the visit, adding that IAEA head Mohamed ElBaradei would "then report in due time" on the results.
What the inspectors saw - and how freely they were allowed to work - will be key in deciding whether six world powers engaging Iran in efforts to reduce fears that it seeks to make nuclear weapons seek a new round of talks with Teheran.
The team's findings will be presented as part of a report to the IAEA's 35-nation governing board. Beyond that, ElBaradei is expected to brief the six countries - the US, Russia, China, Britain, France and Germany - attempting to persuade Iran to freeze enrichment.
