Foreign Minister Avigdor Lieberman was questioned for five hours on Tuesday, the third in less than a week as part of an ongoing police investigation. Police said on Sunday that Lieberman is likely to face charges of money laundering, fraud, bribery and breach of trust.

The new Foreign Minister, who also heads the Yisrael Beiteinu party, will face at least one more round of questioning before the case is closed. Once police gather enough evidence, they will turn the case over to the State Prosecutor's Office.

Law enforcement officials have told Israeli media that they have already gathered hard evidence to support the allegations against Lieberman. If government attorneys decide to indict him, the controversial Foreign Minister may be forced to suspend himself from office.

Police have already questioned several other people accused of involvement in the case, including Lieberman's daughter Michal. Homes and offices have been searched as well.

Lieberman recently filed suit over the investigation, saying police had dragged the case out for an unreasonable amount of time. Police responded by accusing Lieberman of continuing to commit crimes, leaving them with a continuous flow of new material to examine.
