JERUSALEM—Israeli Prime Minister Benjamin Netanyahu was recovering in a hospital on Sunday after an emergency heart procedure, as tens of thousands of supporters and opponents of his government’s judicial overhaul plan held rival rallies ahead of a key vote.
Mr. Netanyahu’s sudden hospitalization for the implant of a pacemaker added another dizzying twist to an already dramatic series of events that have divided his country and are certain to shape Israel’s future. Monday’s vote in parliament is expected to approve the first major piece of legislation in the contentious plan.
