RAMALLAH (AFP) - Palestinian president Mahmud Abbas has told France he is ready to attend a Paris peace conference if Israel accepts talks based on the 1967 borders, an aide told AFP on Sunday. Nimr Hammad, a political advisor to Abbas, said the president had told French Foreign Minister Alain Juppe that he agreed officially to France's proposal to host a peace conference in Paris before the end of July. Juppe raised the possibility of the conference during a visit to Israel and the West Bank last week. "President Abbas told Foreign Minister Juppe that he agrees officially to the French initiative of holding an international peace conference in Paris," Hammad told AFP. But Abbas insisted that participation be conditioned on using the lines which existed before the 1967 Six-Day War as the basis for negotiating future borders, Hammad said. "In order to start negotiations, their basis must be ending the Israeli occupation of Palestinian land occupied since 1967, and the borders of the state will be determined on this basis with land swaps agreed by both the Israeli and Palestinian sides," he said. After meeting Palestinian premier Salam Fayyad in Ramallah on Thursday, Juppe said France was willing to transform a scheduled meeting of international donors into a broader peace conference to help relaunch stalled negotiations. "We would be prepared, on the basis of a request by the (Middle East) Quartet, to organise in Paris... before the end of July, a conference that would not be simply for the donors but a broader political conference involving the negotiation process," he said. Israeli Prime Minister Benjamin Netanyahu said on Sunday that his country was still considering its response. "I heard the proposal brought by French Foreign Minister Alain Juppe," Netanyahu told media at the beginning of Israel's weekly cabinet meeting.
