Tens of thousands of people rallied Tuesday in central Damascus in support of President Bashar al-Asad, a day after he offered a national dialogue to end Syria\'s political crisis, an AFP correspondent said. Omeyyades Square was turned into a sea of pro-Asad demonstrators, waving Syrian flags and the president\'s portrait, chanting, \"We will sacrifice ourselves for you, Bashar!\" State television said a huge demonstration in support of Asad was also being held in Homs, a flashpoint city north of Damascus. In a speech on Monday, three months into anti-regime protests and a crackdown by security forces that has cost hundreds of lives, Asad said a national dialogue could lead to a new constitution but refused to reform Syria under \"chaos.\"
