According to an unnamed Iranian official, Iran has concluded that Israel killed two Iranian scientists via poisoning: Ayoub Entezari, an aeronautical engineer at Ghadir Industrial Turbines Company, on May 31 and Kamran Aghamolaei, a geologist, on June 2. Entezari earned a doctorate in aeronautics and reportedly worked on government projects involving airplane turbines and missiles. Israeli news agencies linked Aghamolaei, who studied for a doctorate in geology at Tarbiat Modares University, to the Natanz nuclear facility, but Iranian sources denied that he had any connection to Iran's government.
