Exiled Syrian opposition leaders have met in Brussels in an attempt to form a united front aimed at toppling Bashar al-Assad. A former Syrian vice-president and the head of the Muslim Brotherhood attended the gathering on Thursday Abdel-Halim Khaddam, the former vice-president who broke with Assad, the Syrian president, last year after serving under his late father Hafez al-Assad, was involved in the talks with nationalists, liberals, Islamists, Kurds and communists, participants said. Husam al-Dairi, Washington-based leader of the Syrian Liberal National Democratic Party said "This is the first time in history that all the opposition movements inside and outside Syria have sat down at one table and agreed on a common plan".He said the coalition of 25 opposition individuals and movements, including the London-based Muslim Brotherhood secretary-general, Ali Saad-al-din Bayanouni, would elect a leader at the Brussels meeting and announce its programme on Friday. Khaddam, who lives in France, chose to stage the meeting in Belgium because he is bound by French law to refrain from political activities under the terms of his political asylum, his son Jihad Khaddam said. "The Syrian people can no longer stand the pressure of the regime and is going to revolt," Jihad Khaddam said, adding that his father had vowed to return home to Damascus after a revolution before the end of this summer. "The coalition is open to everyone. Of course we cannot name the supporters inside for their own safety," he said.
