Iran’s elite Revolutionary Guards Corps (IRGC) has ordered all members to stop using any type of communication devices after thousands of pagers and walkie-talkies used by its Hezbollah allies in Lebanon blew up in deadly attacks last week, two senior Iranian security officials tell Reuters.

One of the security officials said a large-scale operation is underway by the IRGC to inspect all devices, not just communication equipment. He said most of these devices were either homemade or imported from China and Russia.

Iran was concerned about infiltration by Israeli agents, including Iranians on Israel’s payroll and a thorough investigation of personnel has already begun, targeting mid and high-ranking members of the IRGC, added the official, who declined to be identified because of the sensitivity of the matter.

“This includes scrutiny of their bank accounts both in Iran and abroad, as well as their travel history and that of their families,” the security official said. “For now, we are using end-to-end encryption in messaging systems,” he said.

Iran’s foreign, defence and interior ministries were not immediately available to respond to the comments made by the security officials to Reuters.
