President Assad has said the protests are part of a foreign plot |
Syrian security forces have arrested dozens of people after clashes at pro-democracy protests in several cities left at least seven people dead, activists say.
Most arrests came in the southern city of Deraa and the Damascus suburb of Duma, scene of the worst violence.
The government said its security forces were not responsible for the deaths, blaming them on "armed groups".
Coverage of the protests is difficult to gauge because of media restrictions.
Some reports said as many as 15 people had died in Friday's clashes.
A resident told the Associated Press that there was tension in Duma, with security forces patrolling the streets and checking documents.
