Israeli police last week made more than two dozen arrests in a corruption probe in what some say is the most significant anti-corruption operation in the country’s history.

On Dec. 25, Israeli police arrested more than two dozen current and former officials in the probe, including several from the party of Avigdor Lieberman, the foreign minister, Agence France-Presse reported. Officials have been questioned on suspicion of corruption, embezzlement of public funds, and illegal money transfers. According to police, “millions” of shekels of public funds were allegedly transferred to organizations close to Lieberman’s Yisrael Beitenu party.

A total of 18 suspects have been implicated in the scandal, thus far, and remain in custody, and eight others are under house arrest, according to police. Among the individuals arrested include Faina Kirshenbaum, the deputy interior minister; Stas Misezhnikov, former tourism minister; and Yisrael Beitenu's former campaign chief.
