Gaza ground invasion aimed at destroying Hamas, the Palestinian Islamist militant group that unleashed the bloodiest attack in the country's history.
In the eight days since Hamas gunmen killed more than 1,300 Israelis in their surprise onslaught, Israel has responded with a devastating bombing campaign that has claimed over 2,300 lives in Gaza.
Fear and chaos reigned in the 40-kilometre (25-mile) long strip that is one of the world's most densely populated areas and where the UN estimated that one million have been displaced in the war's first week.
Entire Gaza city blocks lay in ruins and hospitals were overflowing with thousands of wounded in the besieged territory, but there were fears of worse to come.
A bereaved and infuriated Israel has massed forces outside the long-blockaded enclave of 2.4 million in preparation for what the army has said would be a land, air and sea attack involving a «significant ground operation».
Israel has also stationed troops and tanks on its UN-patrolled northern border with Lebanon and closed a four kilometre (2.5 mile) wide zone there to civilians after deadly exchanges of cross-border fire with Iran-backed militant group Hezbollah.
Israeli Prime Minister Benjamin Netanyahu visited front line troops in the south near Gaza on Saturday, wearing a flak jacket. «Are you ready for what is coming?» he said.
