Thousands of right-wing Israelis on Thursday blocked a main highway in Tel Aviv as they demonstrated in favor of Prime Minister Benjamin Netanyahu's plan to overhaul the country's judicial system. The crowd was much smaller than the hundreds of thousands of people who have taken to the streets in recent months to demonstrate against the plan. But the gathering had the same effect. Protesters honked their car horns and hoisted blue and white Israeli flags — crippling traffic along the Ayalon highway, the main north-south thoroughfare running through the coastal city.
