OCCUPIED JERUSALEM: Israel dramatically escalated its aerial assault targeting hundreds of Hamas sites in the Gaza Strip Thursday, raising the total number of people killed in this week's offensive to at least 86, according to Gaza Health Ministry.
In response, Gaza militants fired four rockets at occupied Jerusalem, with two shot down over the city and another two hitting open spaces, the Israeli army said.
Witnesses and Palestinian security sources said one rocket struck near the occupied West Bank Jewish settlement of Maaleh Adumim, while a second hit close to an Israeli military prison near Ramallah.
"Four rockets were fired at Jerusalem, of which two landed in open areas and two were intercepted," an army spokesman said without giving further details.
Israeli Prime Minister Benjamin Netanyahu told the Knesset's foreign affairs and defense committee Thursday that a ceasefire with Hamas militants in Gaza is "not even on the agenda."
Meanwhile, UN chief Ban Ki-moon urged for an Israeli-Palestinian cease-fire at an emergency meeting of the U.N. Security Council, a call which was reiterated by Russian President Vladimir Putin in telephone talks with Netanyahu.
Military spokesman Lt. Col. Peter Lerner said Israel struck more than 320 Hamas targets overnight, focusing on underground tunnel networks and rocket launching sites. In all, the military has struck 750 sites since the offensive began on Tuesday.
Israel has mobilized 20,000 reservists for a possible ground operation into Gaza, but for the time remains focused on maximizing its air campaign, Lerner said. A ground invasion could lead to heavier civilian casualties on the Palestinian side and put Israeli ground forces in danger.
Neither side is showing any sign of halting their heaviest fighting since an eight-day battle in late 2012. Israel says that Hamas must cease rocket fire from Gaza for Israel to consider a truce. Militants have fired hundreds of rockets, striking across the length of Israel and disrupting life across the country.
No Israelis have been seriously harmed as the "Iron Dome" defense system has intercepted at least 70 of the projectiles destined for major cities. The system is designed to intercept rockets headed toward populated areas, while allowing others to fall in open areas.
"The ground option needs to be the last option and only if it is absolutely necessary. It is a carefully designed plan of action," Lerner said.
Secretary of State John Kerry, in Beijing for a summit with Chinese leaders, said the U.S. is trying to stem the surging violence in a way that allows the Jewish state to continue defending itself from Hamas rocket fire. He called it a "dangerous moment" for the Mideast, adding he had urged a ceasefire compatible with Israeli self-defense.
Israeli Defense Minister Moshe Yaalon said the operation was going according to plan, with Israel targeting various Hamas interests.
"The military's successes so far have been very significant," he said. "We will continue until they understand that this escalation is not beneficial to them and that we will not tolerate rocket fire toward our towns and citizens."
Palestinian medical officials said one strike early Thursday struck a home in the southern Gaza city of Khan Younis, killing eight members of the Al-Hajj family. Tractors cleared away large piles of debris from the demolished building as one man laid atop a mattress and blankets that remained.
An earlier strike killed eight people who were at a Gaza beach cafe watching the World Cup semifinal match between Argentina and the Netherlands, Mahmoud Sawali said, adding at least two of his brothers were among the dead.
"We only ask of help from God. Here I have two brothers who are martyrs, and I'm looking for the third," he said.
The Israeli military said it was investigating both incidents. It also said it struck a car in Gaza carrying three Islamic Jihad militants involved in firing rockets. The militant group confirmed that its men were killed in the strike. Hamas officials said that the Palestinian side of its border crossing with Israel had also been destroyed in Israeli airstrikes.
Israel accuses militants of deliberately endangering civilians by using homes and other civilian buildings for cover. The military has also directly targeted the offices and homes of known militants that it says are used as command centers. The military says it contacts the families first to ask civilians to evacuate before striking its targets. Many of the dead appear to be relatives of wanted militants according to names of the dead provided by the Palestinians.
