Security forces have been shelling rebel-held towns in Syria, activists say, as President Bashar al-Assad vowed to continue fighting "terrorism".
A boy and five soldiers were reportedly killed as troops launched an assault on the southern town of Herak, a base of the Free Syrian Army.
Activists also said 23 people had died in Homs, five days after the FSA pulled out of the city's Baba Amr district.
A new UN Security Council resolution is meanwhile reportedly being discussed.
The US proposed demanding an end to the violence, first by Syrian government forces and then by armed rebels.
