The Iran Revolutionary Guard Corps has banned its members from using all electronic communication devices in the wake of deadly attacks in Lebanon last week in which pagers and walkie-talkies were used as explosives.

A large-scale operation is currently being executed by IRGC officials to inspect all electronic devices, according to a report from Reuters. The move comes amid concern from Iranian officials that their ranks have been infiltrated by Israeli agents as well as Iranian nationals who may be acting as double-agents focusing on mid and high-ranking members of the IRGC.
