A Syrian opposition activist group, Local Coordination Committees, said President Bashar al-Assad's forces had killed 103 people in the bombardment of Homs and countryside of Hama.
A video uploaded to a social media website on Friday (February 24), showed two wounded people running from a burning building in the town of Idlib.
The town was reportedly being shelled by Syrian government forces.
The video was said to have been filmed on Thursday (February 23).
Reuters can not independently verify the content of the footage.
