Thousands of people have fled their homes amid the bombardments, taking refuge in UN buildings, some of which have been damaged by the Israeli bombardments.
    
The Israeli Defense Forces said today that it warned residents of three areas in Gaza to vacate their homes because of its plans to carry out airstrikes on Hamas and other terrorist groups.
    
The IDF said it used recorded messages, text messages and leaflets to alert the populations in Beit Lahyia, Shuja'iya and Zeitoun, places where it said "a high volume of rocket fire at Israel has originated."
    
Israel's security cabinet has approved plans to destroy Hamas's network of tunnels in Gaza, army radio said.
    
The cabinet also discussed the possibility of a limited ground incursion which would not initially involve entering towns, it said.

 
"Israel has no option but to continue the operation and intensify it," former national security adviser Giora Eiland told army radio. The main dilemma is over a ground operation...It looks like we're rolling in that direction, since air strikes have their limitations," he said.
    
Hamas' rockets continued to fizz over the border, and Israeli airstrikes kept slamming into buildings in Gaza as the death toll climbed higher.
    
The number of Palestinians killed in Gaza in nine days of Operation Protective Edge reached 213 - most of them civilians, according to the United Nations - with at least 1,560 wounded, Palestinian health authorities said.
    
The Israeli military accuses Hamas is taking the people of Gaza hostage by using places like houses, hospitals and schools to hide weapons.

An Egypt mediated truce initiative on Tuesday failed to halt rocket attacks on Israel by Hamas militants and other groups who called it "capitulation and surrender", choosing to continue with rocket and mortar fire.

Israel accepted the Egyptian proposal for a truce, pausing airstrikes for about six hours. But Hamas rejected the plan and kept on launching rockets into Israeli territory.
    
"Hamas have decided to continue, and will pay the price for that decision," Israeli Prime Minister Benjamin Netanyahu said on Tuesday.
    
Israel, which suffered its first fatality Tuesday in a mortar attack at the Ere crossing, said senior Hamas militants had died in strikes on Gaza overnight.

The Israeli army has warned some 100,000 Palestinians in the eastern Gaza Strip to leave their homes.
Army would be carrying out ‘aerial strikes against terror sites and operatives’ in Zeitun and Shujaiya.
The warnings came on the ninth day of Israel's Operation Protective Edge, which aims to stamp out rocket fire from Gaza militants.
Since July 8, militants have fired nearly 1,000 rockets and mortars into the Jewish state and Israel has carried out around 1,500 strikes against targets inside the Gaza Strip.
