There have been angry scenes as opponents of Ariel Sharon’s pullout plan clashed with Israeli security forces. A wall of police and soldiers blocked the path of thousands heading to the territory as part of a major protest march. With the withdrawal set to begin next month, feelings are running high. Demonstrators are battling Israel’s plan to remove all 21 Jewish settlements in Gaza and four of its enclaves in the West Bank. Gaza has been sealed off to all non-resident Israelis since Thursday night.
