In Yemen, the government and an opposition coalition are moving forward with plans to sign an agreement that calls for the president to hand over power. The opposition alliance released a statement on Thursday saying that it may be unable to sign the agreement, if President Ali Abdullah Saleh uses the accord to kill civilians. Some in the opposition say they oppose the agreement because it gives the president a month-long window to resign and because Mr. Saleh and his family would be granted immunity for prosecution. Yemen's main opposition coalition, however, remains behind the plan. EU foreign policy chief Catherine Ashton has welcomed the deal. She says the plan represents Yemen's best chance for addressing its economic, social and security challenges. The agreement was brokered by the Gulf Cooperation Council. It calls for President Saleh to hand over power to a deputy and resign within 30 days of signing the initiative. It would establish a unity government that would include opposition members. Gulf council officials say the agreement may be finalized during a Sunday meeting in Saudi Arabia.
