The Israeli air force targeted rocket launch sites in Gaza hours before the resumption of peace talks with the Palestinians on Wednesday, after rockets were fired from the area, the Israeli army said. \"The raid targeted two rocket launch sites after rockets were fired Tuesday from the Gaza Strip, one of which exploded on Israeli territory,\" said an army spokesman. No one was injured in the attack. \"Hamas must account for any violation of Israeli sovereignty and the terrorist regime that it has put in place will be held responsible for any terrorist activity coming from the Gaza Strip,\" the spokesman added.
