Today's fighting shows how entrenched both sides in Syria's civil war have become. Earlier in the fighting, the sides occasionally attempted to observe holiday cease-fires.
The Britain-based Syrian Observatory for Human Rights says that the rebels fired rockets and mortar rounds at three Damascus neighbourhoods. An amateur video posted online shows three rockets being fired, leaving a trail of dark smoke.
The Observatory adds that the regime bombed rebel areas near the city of Hama, killing three children, and Damascus' Eastern Ghouta district.
