The Israeli air force carried out a raid on the Gaza Strip early Wednesday in retaliation for Palestinian rocket attacks, a military spokeswoman said. Warplanes attacked \"a target situated in the north of the Gaza Strip in retaliation for rockets fired in the past few days against Israeli territory\", she told AFP. A rocket fired from the Gaza Strip came down in southern Israel late Tuesday without causing casualties or damage, another spokeswoman said earlier. A total of 23 rockets have hit Israeli territory since the beginning of the month, the Israeli army said. They have often been followed by reprisal raids.
