Truce takes hold in city of Aleppo

Assad says army won't accept less than 'attaining final victory' against rebels

Relative calm prevailed on Thursday in the Syrian city of Aleppo following a US-Russian agreement to extend a cessation of hostilities that had crumbled after nearly two weeks of violence between rebels and government forces that killed dozens.

Syrian state media said the army would abide by a "regime of calm" in the city that came into effect at 1:00 am for 48 hours.
