The U.N.'s atomic watchdog and other experts say radiological contamination is likely inside a key uranium enrichment site at Natanz that was badly damaged by Israel and then hit by U.S. strikes early Sunday.

Trump says Iran’s nuclear program was obliterated, but questions remain about Iran’s capability and the location of hundreds of pounds of highly-enriched uranium.

The United States has attacked three sites in Iran, inserting itself into Israel’s war aimed at destroying the country’s nuclear program in a risky gambit to weaken a longtime foe that prompted fears of a wider regional conflict.
