Any deal between Tehran and Washington to impose fresh nuclear restrictions on Iran should include "very robust" inspections by the U.N. nuclear watchdog, International Atomic Energy Agency chief Rafael Grossi said on Wednesday. "My impression is that if you have that type of agreement, a solid, very robust inspection by the IAEA ... should be a prerequisite, and I'm sure it will be, because it would imply a very, very serious commitment on the part of Iran, which must be verified," Grossi told reporters.
