Will they find anything Iran's trying to hide? The UN nuclear inspection team, headed by Herman Nackaerts, is back in Tehran today.
FOX News Radio's Emily Wither reports:
It's thought those inspectors in Tehran will be meeting Iranian nuclear scientists and visiting a key military facility there.
It's the second trip in less than a month, the head of the five member-team is remaining upbeat.
(Herman Nackaerts) "We hope to have some concrete results after this trip."
But the pressure for results will be high over fears that Israel is planning a military strike on Iran.
