Syrian protesters call for change
Thousands of demonstrators have marched through the southern Syrian city of Deraa calling for greater freedoms.
The demonstrators had set fire to buildings including the offices of the country's ruling Baath Party.
There have been days of violent clashes between anti-government protesters and security forces in the city, leaving at least four people dead on Friday alone.
The BBC's security correspondent Frank Gardner describes amateur video of protests on Sunday.
