In a press conference in the Defense Ministry in Tel Aviv on Tuesday, Defense Minister Amir Peretz told reporters that, following an intensive three-day investigation, the IDF "has enough findings to demonstrate that [the Friday death of seven Palestinian civilians in an explosion on the Gaza beach] was not of our doing." Peretz also expressed "regret that today, during an event in which our forces acted against an attempt to launch a Grad missile into Israel, innocent Palestinian citizens were also killed." Even so, he said, "All the organizations acting against us are trying to hurt our civilians. They act from within population centers through the conscious knowledge that they are endangering the population." Peretz called on Palestinians "not to allow them to act from inside population centers."
