Jerusalem – Prime Minister Benjamin Netanyahu was indicted Thursday in a series of corruption cases, throwing Israel’s paralyzed political system into further disarray and threatening his 10-year grip on power. He rejected calls to resign, angrily accusing prosecutors of staging “an attempted coup.”

The first-ever charges against a sitting Israeli prime minister capped a three-year investigation, with Attorney General Avichai Mandelblit indicting Netanyahu for fraud, breach of trust and accepting bribes.

“A day in which the attorney general decides to serve an indictment against a seated prime minister for serious crimes of corrupt governance is a heavy and sad day, for the Israeli public and for me personally,” Mandelblit, who was appointed by Netanyahu, told reporters.

The indictment does not require the 70-year-old Netanyahu to resign, but it significantly weakens him at a time when Israel’s political parties appear to be limping toward a third election in under a year.

An ashen-faced Netanyahu appeared on national TV late Thursday, claiming he was the victim of a grand conspiracy by police and prosecutors who had intimidated key witnesses into testifying against him.
