The London-based Syrian opposition group, Syrian Human Rights Observatory, said the family was killed in a coalition strike on the village of Daly Hassan, in the Northeast of Aleppo province, AFP reported.
Their deaths "bring the number of Syrian civilians killed in coalition air strikes since September 23 to 148, including 48 children and 32 women," the monitor said.
In May, the Observatory reported at least 64 civilians — nearly half of them children — had been killed in US-led air strikes in the village of Birmahle in Aleppo province.
The Pentagon has generally denied that US-led coalition strikes have killed any civilians, despite persistent reports of numerous civilian deaths.
