Protests erupted in Israel on Sunday following the deaths of six hostages in Gaza as frustration mounted with the country's leadership for failing to secure a cease-fire deal that would free Israeli captives.

Crowds estimated by Israeli media to number up to 500,000 strong demonstrated in Jerusalem, Tel Aviv and other cities, demanding that Prime Minister Benjamin Netanyahu do more to bring home the remaining 101 hostages.

Israel estimates about a third of them are dead.
