Palestinian students shout pro-Palestinian slogans during a demonstration to protest Israel's attack on the Gaza Strip, in the Palestinian refugee camp of Ein el-Hilweh, near the southern port city of Sidon, Lebanon, on Tuesday Jan. 6, 2009. Israel ignored mounting international calls for a cease-fire and said it won't stop its crippling 10-day assault until "peace and tranquility" are achieved in southern Israeli towns which they say are in the line of Palestinian rocket fire.
