A Palestinian man inspects the damage by an Israleli strike at the Inteiz family house in the Shajaiyeh neighborhood of Gaza City, northern Gaza Strip. Three members of the family were killed overnight when a tank shell hit the family house, according to the family. Israeli troops pushed deeper into Gaza on Friday to destroy rocket launching sites and tunnels, firing volleys of tank shells and clashing with Palestinian fighters in a high-stakes ground offensive meant to weaken the enclave's Hamas rulers.Lefteris Pitarakis/The Associated Press
