Amateur footage of what is believed to be the city of Hama as Syrian forces attack.
Syrian security forces have cracked down on anti-government protests across the country, killing 100 people in the city of Hama alone, reports say.
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.
US officials accused the government of waging "full-on warfare" on its people.
The assault was a last act of utter desperation by the Syrian government, said JJ Harder, a US embassy spokesman in the capital, Damascus.
