Turnout so far highest on record as Israelis vote in pivotal election
The elections - the first since the Hamas-led attacks on Israel and the wars which followed - are widely seen as a referendum on Benjamin Netanyahu.
Turnout so far is at record levels, as Israelis vote in what many view as one of the most pivotal elections in the country's history.
Polling published on Friday suggests incumbent Benjamin Netanyahu is almost neck-and-neck with former military chief Gadi Eisenkot in the race to become prime minister.
But neither of their political blocs are projected to win the 61 seats needed to form a majority government - meaning weeks or months of political wrangling may lie ahead.
Another dominating issue has been conscription, with Netanyahu's government failing to enforce a Supreme Court ruling that ultra-Orthodox Jewish men in full-time religious study should be conscripted to the military - a highly divisive move as thousands of others have been conscripted to fight in recent wars.
