A Palestinian man cries over the body of his son following an Israeli air strike in Gaza December 27, 2008. Israeli warplanes and combat helicopters pounded the Hamas-ruled Gaza Strip on Saturday, killing at least 155 people in the bloodiest day for Palestinians in more than 20 years. Palestinian militants responded with rocket salvoes that killed an Israeli man and wounded several others, medics said. REUTERS/Ismail Zaydah (GAZA)
