JERUSALEM (AFP) - Israel may agree to a West Bank settlement freeze by mid-September and is discussing the technical aspects of a deal with the United States, EU foreign policy chief Javier Solana said on Monday. Solana also said after meeting the Israeli premier that a summit between the US, Israeli and Palestinian leaders to relaunch the dormant peace process could take place on the sidelines of the UN General Assembly at the end of September. I spoke to the prime minister (Benjamin Netanyahu)... I got the clear sentiment that there is a possibility to get to an agreement before the beginning of the General Assembly that will allow us to resume negotiations, he told reporters. I hope we will arrive at some agreement sufficiently constructive (for) the meeting in New York of three parties to take place, added Solana, who was meeting Israeli and Palestinian leaders on Monday as part of a regional tour. Meanwhile, Israels hardline Foreign Minister Avigdor Lieberman said on Monday that any Middle East peace talks should be open-ended and vowed to respond if Palestinians make good on plans to create a de facto state of their own. A positive dynamic must be created between both sides, without committing to target dates for an overall arrangement, Lieberman was quoted by his office as telling EU foreign policy chief Javier Solana and Mideast Quartet envoy Tony Blair.
