The Israeli army shelled six rocket launch sites in the northern Gaza Strip in an attempt to push them back. Army sources said that even if the rocket-launch cells are pushed back they will still be able to hit Israeli territory, although not as far north as when they fired from former settlements. Deputy Prime Minister Ehud Olmert said that the disengagement had increased the military’s flexibility of response. “I believe that these means will significantly reduce the shelling,” he said. “There is nothing that can totally prevent it, unless those who fire decide to stop firing.” Palestinian Authority Chairman Mahmoud Abbas condemned the move, saying it was tantamount to re-occupying land Israel gave up in September.
