Lebanese students, carry mock rockets as they shout pro-Palestinian slogans during a demonstration held by Hezbollah to protest Israel's attack on the Gaza Strip, in front of the United Nations house, in Beirut, 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 in the line of Palestinian rocket fire.
