Riyadh

      Representatives of Arab nations participating in the Arab League summit in Riyadh have unanimously agreed to reinvigorate the Saudi peace initiative, without changing its clauses. Saudi King Abdullah opened the summit with a strongly worded speech, painting a bleak picture of the crises and bloodshed in the region - Lebanon, Iraq and Sudan - and lecturing the leaders that it was time to act. "The real blame should be directed at us, the leaders of the Arab nation," he said. "Our constant disagreements and rejection of unity have made the Arab nation lose confidence in our sincerity and lose hope." Arab League Secretary-General Amr Moussa rejected amending the peace offer, saying, "They tell us to amend it, but we tell them to accept it first, then we can sit down at the negotiating table." But he said the Arabs must "do more to convince" the Israelis on the offer. Palestinian Authority Chairman Mahmoud Abbas voted in favor of the initiative, although Palestinian Prime Minister Ismail Haniyeh of Hamas abstained in the vote. Saudi Arabia's King Abdullah called at the summit for an end to the international blockade on the Palestinian government and to revive efforts to resolve the Arab-Israeli conflict.EU foreign policy chief Javier Solana, a guest at the Riyadh summit, said both sides should show flexibility(21,45)
