Activists say 77 people died in the coastal city of Baniyas a day after 72 were killed at the nearby village of al-Bayda.
Unverified mobile phone footage posted on the internet shows the bodies of women and children.
Local activist and opposition groups have accused the government of launching a campaign of sectarian cleansing, but the government said it had fought back "terrorist groups" and restored peace and security to the area.
