According to former intelligence official Abdullah Shahbazi, that the domestic security crackdown in Iran had become so intense, top officials "change safe houses every night and avoid using phones, fearing assassination.

"What became clear to all of us is that there is prolonged ground activity by the Mossad network inside Iran," he told the British news outlet.

According to the report, Tehran had changed its appearance overnight since a US-brokered ceasefire ended a two-week war with Iran, with the Iranian capital now being regularly patrolled by armed forces from the IRGC and the Basij militia. Police are reportedly regularly raiding homes and arresting citizens without apparent cause.
