TEHRAN, Iran - Iran has buried a slain nuclear expert, whom Tehran officials claim was killed by the U.S. and Israel as part of a covert operation aimed at stopping the country's nuclear program.
State TV showed thousands of people attending the funeral of Mostafa Ahmadi Roshan, a chemistry expert and a director of the Natanz uranium enrichment facility in central Iran.
Iran's Supreme Leader Ayatollah Ali Khamenei, who has the final say on all state matters, said those behind the Wednesday assassination would be punished.
While the U.S. has denied any involvement, Israeli officials have hinted at covert campaigns against Iran without making any direct admissions. A hard-line Iranian newspaper Thursday called for retaliation against Israel.
