At the same time, Gaza militants continued their barrage of rocket fire at Israel, firing more than 100, including two at Tel Aviv. More than 10 Israelis were injured by shrapnel, two moderately, according to police spokesman Mickey Rosenfeld. Israel’s “Iron Dome” rocket-defense system shot down at least 30 rockets, including the ones aimed at Tel Aviv. Israel’s announcement Sunday that it was widening its campaign to target homes of militants 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. Israel launched the offensive Wednesday in a bid to end months of intensifying rocket fire from the Hamas-ruled Gaza Strip. The day’s deadliest strike hit the home of the Daloo family in Gaza City, reducing the structure to rubble. Frantic rescuers pulled the bodies of several children from the ruins of the house, including a toddler and a 5-year-old, as survivors and bystanders screamed in grief. Later, the bodies of the children were laid out in the morgue of Gaza City’s Shifa Hospital. Among the 11 dead were four small children and five women, including an 80-year-old, Gaza health official Ashraf al-Kidra said. In a statement, U.N. Secretary-General Ban Ki-moon said he was “deeply saddened” by the deaths of the civilians and “alarmed by the continuing firing of rockets against Israeli towns.” Israeli military spokesman Brig Gen. Yoav Mordechai told Channel 2 TV that the Israeli navy had targeted the building and killed a “global jihad” militant.
