One Israeli suspect, Vladislav Victorsson, 30, was arrested on Oct. 14 along with his 18-year-old girlfriend in the Israeli city of Ramat Gan near Tel Aviv. He had been jailed in 2015 for sex with minors as young as 14, according to a court indictment from that time.

In a major development, Israeli authorities have arrested almost 30 individuals, mostly Jewish citizens, accused of spying for Iran. These arrests are part of one of the most significant espionage operations Israel has faced in decades.

In the months before Iranian ballistic missiles struck the Nevatim Airbase in October, Iran dispatched spies to film and photograph the site in southern Israel, according to Israeli authorities.
