Iranian authorities have carried out a wave of arrests and multiple executions of people suspected of links to Israeli intelligence agencies, in the wake of the recent war between the two countries.

It comes after what officials describe as an unprecedented infiltration of Iranian security services by Israeli agents.

Authorities suspect information fed to Israel played a part in a series of high-profile assassinations during the conflict. This included the targeted killings of senior commanders from the elite Islamic Revolutionary Guard Corps (IRGC) and nuclear scientists, which Iran attributes to operatives of Israel’s Mossad intelligence agency working inside the country.
