Israeli Prime Minister Ariel Sharon has accused groups opposed to his Gaza pull-out plan of trying to incite a civil war. Sharon said at the start of Sunday's cabinet meeting that relevant measures to prevent the groups had to be taken. He said the groups were "in essence aimed at inciting civil war." "I call upon those of you in charge of security matters, to take all necessary steps," he added. His call comes after settler leaders warned on Friday that withdrawal plans could plunge Israel into civil war. A group of prominent hardliners urged security forces to disobey orders to dismantle settlements. Far-right groups are against ceding land captured by Israel in the 1967 war and say that doing so will "reward Palestinian terror." **Protest*** Tens of thousands of Israeli settlers and their supporters are set to rally in the centre of Jerusalem in protest against the Gaza pullout plan. The main settlers' organisation, Yesha, is predicting that more than 100,000 people will gather at Zion Square on Sunday from 1600 GMT in the second mass show of opposition to the plan in recent weeks. Under Sharon's plan, Israeli occupation forces will leave the Gaza Strip by September 2005 after tearing down 21 illegal Jewish settlements in the region and evacuating 8000 residents. The same fate awaits four illegal settlements in the north of the West Bank. Sharon has shrugged off all attempts to block the Gaza pullout so far, including a defeat in a referendum among members of his Likud party and a protest in late July which saw more than 100,000 people form a human chain linking Gaza to Jerusalem. **PHOTO CAPTION*** Palestinians carry a youth wounded by Israeli gunfire in the West Bank town of Bethlehem during an arrest operation.
