Jewish settlers have vowed they would stage mass protests to fight against eviction from Gaza after losing their last hope of derailing Prime Minister Ariel Sharon's withdrawal plan in parliament.
"We won't let this (withdrawal) happen," said settler spokesman Eran Sternberg when parliament passed Sharon's 2005 state budget, removing the last legislative hurdle to uprooting the settlers from July.
"Hundreds of thousands will soon make their way to (our areas). They will prove this pullout is impossible.
The police cannot handle hundreds of thousands of people, they will face many challenges," said Mr Sternberg.
Settler leaders have said they will not encourage violence, but have warned that the decision to give up settlements - welcomed by most Israelis - could trigger a civil war.
"We have no doubt there will be people killed, how many I couldn't say," said Ron Bakshi, who lives in the settlement of Neve Dekalim, which translates from Hebrew as "Beautiful Palms".
"The young people are taking this harder than their parents. They were born here, this has been their entire life. They are liable to do very difficult things."
Under Mr Sharon's plan, Israel will remove all 8,500 settlers from the Gaza Strip - land that many of them see as a biblical birthright and where they live in lush and heavily defended suburban enclaves among 1.3 million Palestinians.
Four of 120 West Bank settlements will also go when for the first time Israel gives up settlements on land it captured in the 1967 Middle East war. Palestinians want Gaza and the West Bank for an independent state as part of any peace deal.
