RAMALLAH, Feb. 27 (Xinhuanet) -- Palestinian leader Mahmoud Abbas will leave the West Bank city of Ramallah on Sunday for London viaJordan to attend a two-day international conference on the Middle East due to open Tuesday, Palestinian sources said.

    The London conference comes against the backdrop of a suicide bombing attack in Tel Aviv on Friday night that left four Israelisdead and some 50 wounded, the first such attack in the past four months, dampening hope to revive the stalled roadmap peace plan which calls for the creation of an independent Palestinian state.

    UN Secretary General Kofi Annan, US Secretary of State Condoleezza Rice and the European Union foreign policy chief Javier Solana as well as representatives of 25 nations are scheduled to take part in the conference.

    The meeting, sponsored by British Prime Minister Tony Blair, will discuss how to help push Palestinian reforms, economic and security rebuilding. Enditem
