Iranian authorities have announced the arrest of 20 individuals accused of working as operatives for the Mossad spy agency in recent months. The judiciary has stated that those found guilty will face severe punishment, aiming to set a strong example. Some of the suspects have already had charges dropped and were released, though officials did not specify how many. This announcement comes after the execution of a nuclear scientist, Rouzbeh Vadi, who was convicted of spying for Israel and passing sensitive information. Executions for espionage have risen sharply in Iran this year, with at least eight carried out recently. Further details about the cases are expected once investigations conclude.
