A few days after insurgents in Syria overthrew President Bashar Assad, his ruling Baath party announced it was freezing its activities, marking a stunning change in fortunes for the political group that had ruled for more than six decades. Many members of the party's leadership have gone into hiding and some have fled the country. In a symbolic move, Syria's new rulers have turned the former party headquarters in Damascus into a center where former members of the army and security forces line up to register their names and hand over their weapons.
