Tens of thousands of Israelis gathered in Tel Aviv on Saturday night to protest plans by Prime Minister Benjamin Netanyahu’s new government to overhaul the judicial system, measures that opponents say imperil the country's democratic fundamentals. Israeli media, citing police, said some 100,000 people were out protesting. The protest followed another demonstration last week that also drew tens of thousands in an early challenge to Netanyahu and his ultranationalist and ultra-Orthodox government — the most right-wing in Israeli history.

Netanyahu has pledged to press on with the changes despite the opposition. Protesters filled central streets in the seaside metropolis, raising Israeli flags and banners that read “Our Children will not Live in a Dictatorship” and “Israel, We Have A Problem.” “This is a protest to defend the country,” said opposition leader and former Prime Minister Yair Lapid, who joined the protest. “People came here today to protect their democracy.” “All generations are concerned. This is not a joke,” said Lior Student, a protester. "This is a complete redefinition of democracy.” Other protests took place in the cities of Jerusalem, Haifa and Beersheba. In addition to the protests, pressure has built up on Netanyahu’s government after the country’s attorney general asked Netanyahu to fire a key Cabinet ally following a Supreme Court ruling that disqualified him from holding a government post because of a conviction of tax offenses. While Netanyahu was expected to heed the court ruling, it only deepened the rift in the country over the judicial system and the power of the courts. Earlier this week, Netanyahu, who is on trial for corruption, vowed to continue with the judicial overhaul plans despite the protests. Opponents say the changes could help Netanyahu evade conviction in his corruption trial, or make the court case disappear altogether.

Defense Minister Yoav Galant, a member of Netanyahu's Likud party, ordered the removal of the outpost, upsetting a pro-settlement Cabinet member who had issued a directive to postpone the eviction pending further discussions.
