At least 19 people were killed overnight by Syrian rebel fire on government-controlled parts of the northern city of Aleppo, a monitor said on Friday.
The Syrian Observatory for Human Rights said the dead included at least five children, three of whom were killed with their mother when a rocket hit the car they were in.
The Britain-based group said at 32 people were wounded in Thursday night's violence in the western part of the city.
Once Syria's economic hub, Aleppo has been ravaged by fighting that began there in mid-2012.
