News agencies report that Syrian troops have shot dead three people and wounded several others in the western border town of Tall Kalakh.
A woman who had fled to the Lebanese border said she saw soldiers and militia and heard the sound of machine guns in Tall Kalakh.
The reported deaths, based on witness accounts, come a day after thousands of people protested against the government in the town, which is about 160 kilometers north of Damascus.
At least three people were shot dead in Syria on May 13 by security forces despite an order by President Bashar al-Assad for them not to open fire on demonstrators.
The United States on May 13 expressed "outrage" over Syria's crackdown on protests, saying chances were narrowing for Damascus to respond to its people's demands for democracy.
