JERUSALEM — Prime Minister Netanyahu and his allies on Thursday denounced as “anarchists” protesters who massed outside a Tel Aviv salon where his wife was getting her hair done — a chaotic end to a day of demonstrations against the government’s plan to overhaul the judiciary.

The incident late Wednesday at Tel Aviv reflected Israel’s divide over the overhaul, seen by opponents as an existential threat to the country. Demonstrators outside the salon chanted, “shame, shame” — but did not try to force their way inside. Hundreds of police were sent to the scene and eventually escorted her into a limousine.
