Another crackdown on dissidents has left at least 20 people dead in the Syrian city of Homs, according to activists.
Footage shot by government opponents claims to show the carnage after troops in tanks fired mortars and machine guns into residential areas. However, verifying the video is difficult as foreign media are banned from reporting within the country.
This latest attack on Monday morning came less than 24 hours before a group of Arab League monitors was due to arrive and oversee the scaling back of government force. The monitors are expected to visit Homs on Tuesday.
The western city has been the flashpoint for many violent scenes since the movement against President Bashar al-Assad took hold in March.
Fighting in Homs has escalated since a suicide bombing in the capital Damascus killed 44 people on Friday.
