At least six people have been killed by security forces in central Syria on the first day of the Muslim Eid al-Adha holiday, activists have claimed.
Five of the deaths occurred in the flashpoint central province of Homs, one of the main centres of protest and reprisal during the seven-month uprising against president Bashar Assad.
The British-based Syrian Observatory for Human Rights says troops killed a sixth civilian in the city of Hama during raids in the restive region.
Troops also fired live ammunition to disperse protesters near Damascus and in the country's north. There were no immediate reports of casualties.
The violence is adding to fears that a peace plan brokered by the Arab League was unravelling just days after Damascus agreed to halt its crackdown.
