The defense establishment believes that Iranian agents followed an engineer in an unnamed Israeli "defense institution" in the course of a conference that was held in a foreign country.
Channel 10 reported Wednesday that the engineer realized he was being followed and filmed in the course of the conference. He reported the matter to the local security officer, in accordance with the instructions he received before leaving Israel.
The security officer reported to the security officer of that "defense institution" that Iranian agents do indeed appear to be following the engineer. The security officers decided to move the engineer from the hotel he was staying in to another hotel.
The engineer was reportedly somewhat shaken by the incident.
