A Palestinian gunman protests against the Israeli attacks on the Gaza Strip, in the Palestinian refugee camp of Ein el-Hilweh near the southern port city of Sidon, Lebanon, Saturday, Dec. 27, 2008. Israeli warplanes retaliating for rocket fire from the Gaza Strip pounded dozens of security compounds across the Hamas-ruled territory in unprecedented waves of airstrikes Saturday, killing at least 155 and wounding more than 310 in the single bloodiest day of fighting in recent memory.
