Armed groups killed entire families, including women and children, during an outbreak of sectarian violence in Syria last week, the United Nations human rights office said on Tuesday.

The Syrian Network for Human Rights said armed groups and foreign fighters aligned with the government but not integrated into it were largely responsible for the sectarian violence.

Summary executions and other atrocities have taken place in Syria’s coastal region following insurgent attacks on Syrian security forces and during subsequent government security operations, with the Alawite community bearing the brunt of the violence.

A Syrian military operation against remnants of the former Assad regime has now ended, having sparked some of the worst violence seen in the country in years.

Entire families including women and children were killed in Syria's coastal region as part of a series of sectarian killings by rival groups during an insurgency by Bashar al-Assad loyalists, the U.N human rights office said on Tuesday.
