Israeli police have arrested a 26-year-old army reservist who served on the Iron Dome air defence system on suspicion of passing secrets to Iran.
The arrest comes as Israel and the United States are engaged in a war with Iran that has spread across the Middle East.
Raz Cohen, a resident of Jerusalem, was recently arrested on suspicion of committing security offenses involving contact with Iranian intelligence.
According to Israeli police, over several months, Cohen maintained contact with Iranian intelligence operatives and was asked to carry out various security missions, including passing on sensitive security information.
The war between Israel and Iran has resulted in the deaths of 19 civilians, including four Palestinian women in the occupied West Bank, and significant damage to strategic sites.
