"If the government decides to lead Israel with open eyes into a constitutional crisis, we will shut down the companies and launch a public struggle together with all the strength of Israeli society," the Israeli high-tech business forum, which includes dozens of the largest high-tech companies and leading venture capital funds, said Friday afternoon. "We call on [Prime Minister Benjamin] Netanyahu to stop a moment before falling into the abyss."

Histadrut Chief Arnon Bar David warned on Friday of "anarchy under government auspices," says refusal to comply with High Court ruling is a "red line," and vows that he will not "sit quietly while the State of Israel is being dismantled."

Opposition parties Yesh Atid, National Unity, Yisrael Beytenu, and The Democrats submitted a petition to the High Court of Justice on Friday demanding an injunction against the dismissal of Shin Bet chief Ronen Bar.

The petition came following the cabinet's unanimous Thursday vote to end the agency's chief term, following Prime Minister Benjamin Netanayhu's decision to put forward such a proposal to the cabinet.

This is a developing story.
