Israel's former foreign minister Avigdor Lieberman was formally indicted on Sunday on charges of breach of trust and fraud, allegations that could hurt his political future if he is convicted.

Lieberman resigned this month after he was informed of the pending charges. The justice ministry later revised the wording, though not the charges, and said it filed the indictment in a Jerusalem court on Sunday.

Lieberman is accused of advancing a former ambassador after he relayed information to the foreign minister about a criminal investigation into his business dealings. He denies wrongdoing.

His Yisrael Beiteinu party is running with prime minister Binyamin Netanyahu's Likud in forthcoming elections, and he is expected to serve as a legislator in the next parliament.

Meanwhile, Israel's supreme court unanimously rejected an election committee's attempt to disqualify an Arab legislator from running for parliament again next month because she took part in a flotilla that tried to breach Israel's naval blockade of the Hamas-run Gaza Strip.

The legislator, Hanin Zoabi, enraged many Israelis by joining the Turkish-led flotilla, which was stormed by Israeli naval commandos who clashed with pro-Palestinian activists, killing nine.
