By Tuesday, 133 Palestinians, including at least 54 civilians, were killed since Israel began an air onslaught that has so far included nearly 1,500 strikes. Some 840 people have been wounded, including 225 children, Gaza health officials said.
Five Israelis, including an 18-year-old soldier and a civilian contractor who worked for the military struck by rocket fire Tuesday, have also been killed and dozens wounded since the fighting began last week, the numbers possibly kept down by a rocket-defense system that Israel developed with U.S. funding. More than 1,000 rockets have been fired at Israel this week, the military said.
Late Tuesday, a Palestinian rocket hit a house in the central Israeli city of Rishon Lezion, wounding two people and badly damaging the top two floors of the building, police spokesman Micky Rosenfeld said. In other violence, a 60-year-old Israeli woman was seriously wounded in a firebombing attack as she drove in the West Bank, police said.
With the death toll rising, the international community stepped up efforts to bring a halt to the fighting that began last Wednesday with an Israel's assassination of the Hamas military chief.
"If a long-term solution can be put in place through diplomatic means, then Israel would be a willing partner to such a solution. But if stronger military action proves necessary to stop the constant barrage of rockets, Israel wouldn't hesitate to do what is necessary to defend our people," Netanyahu said during a joint press conference in Jerusalem with visiting U.N. chief Ban Ki-moon.
Ban condemned Palestinian rocket attacks, but urged Israel to show "maximum restraint."
"Further escalation benefits no one," he said.
Minutes before Ban's arrival in Jerusalem from Egypt, Palestinian militants fired a rocket toward Jerusalem, just the second time it has targeted the city. The rocket fell in an open area southeast of the city.
Jerusalem had previously been considered beyond the range of Gaza rockets - and an unlikely target because it is home to the Al-Aqsa Mosque compound, Islam's third-holiest shrine.
Earlier Tuesday, a man identified as Hamas' militant commander urged his fighters to keep up attacks on Israel. Speaking from hiding on Hamas-run TV and radio, Mohammed Deif said Hamas "must invest all resources to uproot this aggressor from our land," a reference to Israel.
Israeli warplanes dropped leaflets on several Gaza neighborhoods asking residents to evacuate and head toward the center of Gaza City along specific roads. The army "is not targeting any of you, and doesn't want to harm you or your families," the leaflets said. Palestinian militants urged residents to ignore the warnings, calling them "psychological warfare."
The Israeli military relies on a network of informants to identify its targets. Masked gunmen publicly shot dead six suspected collaborators with Israel in a large Gaza City intersection Tuesday, witnesses said. An Associated Press reporter saw a mob surrounding five of the bloodied corpses shortly after the killing.
Clinton was also scheduled to meet with Palestinian President Mahmoud Abbas in the West Bank and Egyptian leaders in Cairo Wednesday. Turkey's foreign minister and a delegation of Arab League foreign ministers traveled to Gaza on a separate truce mission. Airstrikes continued to hit Gaza even as they entered the territory.
