The Israeli peace camp has launched the biggest protest in years with more than 100,000 people protesting on Saturday and demanding the country leave Gaza, after Palestinian militants dealt Israel's army its deadliest blow since 2002. Crowds at Tel Aviv's main square added to the growing call for withdrawal from the war-torn territory. The killing of 13 soldiers by militants in the Gaza strip last week has deepened already strong support in Israel for Prime Minister Sharon's Gaza pullout plan which is being delayed by hardliners in his right wing Likud party.
