Syrian activists claimed government forces have killed at least seven anti-government demonstrators in protests after Friday prayers.
The Syrian Observatory for Human Rights, which is based in the UK said four were shot dead in a suburb of Homs, and three more died in the capital Damascus.
The popular movement to oust President Bashar al-Assad has continued for six months against the deployment of police and heavily armed troops.
Assad has promised a parliamentary election, and he has said he will give citizenship to tens of thousands of Syrian Kurds. But Russia’s president said the government should step down if it cannot implement the reforms it has promised.
Protesters burned the Russian and Chinese flags near Hamah after the two superpowers blocked a European attempt at the UN to pass a Security Council resolution urging Assad to end his crackdown.
The United Nations estimates that nearly 3,000 people have been killed in the uprising.
Assad’s opponents claim his promises of change are hollow, and his administration has forfeited all legitimacy.
