Iran has arrested 20 individuals accused of being operatives for Israel's Mossad spy agency, according to statements from the Iranian judiciary. These arrests come amid heightened tensions following a series of Israeli airstrikes in June that killed over 30 Iranian nuclear scientists. Iran has responded by relocating surviving nuclear experts to secure locations with round-the-clock protection. Reports indicate that Israel maintains a list of approximately 100 Iranian nuclear scientists it considers high-value targets. Among the recent developments, Iran executed Rouzbeh Vadi, a nuclear scientist accused of spying for Israel. The judiciary has also noted that charges against some of the 20 alleged spies have been dropped and those individuals released, though specific numbers were not provided. Iranian officials have warned that those arrested will face no leniency and will be made examples of, underscoring the ongoing espionage concerns between the two countries.
