US President Barack Obama has said he is appalled by the brutal attacks by Syrian forces on civilian protesters.
Witnesses said tanks moved into Hama at dawn, shelling civilians. Other towns also erupted in violence in one of the bloodiest days since protests began.
The government said troops had been sent in to Hama to remove barricades erected by the protesters.
