It's not much of a surprise that Assad is a liar and will continue the bloodshed in Syria. The only surprise is that anyone believed Assad would live up to his word. The Guardian:
Hopes for a peaceful end to the Syrian crisis were fading rapidly on Sunday after President Bashar al-Assad refused to meet Tuesday's deadline for withdrawing his forces from flashpoints across the country without guarantees from the opposition to stop fighting first.
Kofi Annan, the former UN secretary-general, had called for a pullout to be completed by Tuesday morning with a ceasefire taking effect 48 hours later as the first stage in a six-point international plan for political negotiations between the Assad regime and its opponents.
Amid evidence of continuing government operations, Syria's foreign ministry said it was demanding written guarantees that "armed terrorist groups" would lay down their weapons.
