REPUBLIKA.CO.ID, GAZA CITY - An Israeli envoy held talks with Egyptian officials Sunday on a ceasefire in his country's offensive on Gaza as Israel widened the range of its targets, striking more than a dozen homes of Hamas militants and two media officials. Seven civilians were killed, including five children, in the conflict's highest one-day civilian toll yet, according to security officials and witnesses.

Upon arrival at Cairo's international airport, the Israeli official was whisked away directly from the tarmac and taken to talks with Egyptian authorities, Egyptian security officials said, speaking on condition of anonymity because they were not authorized to talk to the press. They did not identify the Israeli official.

Egypt has been leading international efforts to broker a truce since Israel launched its offensive five days earlier aimed at stopping Gaza rocket attacks. But Israel and Gaza's militant Hamas rulers remain far apart on any terms.

Hamas is linking a truce deal to a complete lifting of the border blockade on Gaza imposed since Islamists seized the territory by force. Hamas also seeks Israeli guarantees to halt targeted killings of its leaders and military commanders. Israeli officials reject such demands. They say they are not interested in a "timeout," and want firm guarantees that the rocket fire will finally end. Past ceasefires have been short lived.

Netanyahu ready to expand the operation

As the offensive moved forward, Israel found itself at a crossroads — on the cusp of launching a ground offensive into Gaza to strike an even tougher blow against Hamas, or pursuing Egyptian-led truce efforts.

"The Israeli military is prepared to significantly expand the operation," Israeli Prime Minister Benjamin Netanyahu declared at the start of the weekly Cabinet meeting.

Expanding targets to strike the homes of suspected commanders appeared to mark a new and risky phase of the operation, given the likelihood of civilian casualties in the densely populated territory of 1.5 million Palestinians.

New strikes on Sunday leveled homes in Gaza, burying residents under the rubble as rescuers frantically dug for survivors. In all, 57 Palestinians have been killed, including 24 civilians, and more than 400 civilians have been wounded, medics say.

At the same time, Gaza militants continued their barrage of rocket fire, firing more than two dozen at Israel on Sunday, including a longer-distance projectile that targeted Tel Aviv for a fourth straight day. One rocket damaged a home in the southern city of Ashkelon, punching a hole in the ceiling. Israel's "Iron Dome" rocket-defense system shot down seven rockets, including the one aimed at Tel Aviv, police spokesman Mickey Rosenfeld said. Eight Israelis were wounded by shrapnel Sunday, one of them moderately.

Israel launched the operation last Wednesday by assassinating Hamas' military chief and carrying out dozens of airstrikes on rocket launchers and weapons storage sites in response to mounting rocket attacks. Over the weekend, the operation began to target Hamas government installations as well, including the offices of its prime minister.

Israel blames Hamas for civilian casualties, saying the group uses residential areas for cover and puts civilians in danger. It also accuses Hamas of intentionally targeting Israeli civilians with its rocket fire. Three Israelis, all civilians, have died in the fighting, and rocket attacks on Israeli cities continued interrupted Sunday.

A strike Sunday on a three-story home in the northern Gaza town of Beit Lahiya killed a 3-year-old girl and a 5-year-old boy from the same family. Hamas security officials said three missiles struck the house, owned by a family that has members who are involved in militants' rocket squads. It was not known if any militants were in or near the house at the time of the strike.

A strike in Gaza City flattened the home of a family known for its support for Hamas, killing three women and a fourth civilian, according to Gaza health official Ashraf al-Kidra.

Another strike in the city brought down a home near a Hamas police station in the Tufah neighborhood. Rescue workers pulled out the body of a dead woman, along with several surviving members of her family.

In the Shati refugee camp near Gaza City, a missile struck the car of a Hamas militant outside his home, killing him and an 11-year-old girl passing by at the time, al-Kidra said.
