According to witnesses, Syrian security forces fired on people gathered for funerals on Saturday.
They were in funeral processions for the 75 ore more people killed on Friday in mass protests against the country's authoritarian president Bashar Assad. More than 300 people have been killed since the uprising started more than five weeks ago.
The violence has prompted two Syrian lawmakers to resign in disgust over the killings.
The lawmakers, Nasser Hariri and Khalil Rifai, are from the southern region of Daraa that unleashed the protest movement in mid-March after teenagers were arrested there for scrawling anti-regime graffiti on a wall.
The resignations were exceedingly rare in Syria, where nearly all opposition figures are either jailed or exiled.
The increasing bloodshed has drawn international condemnation.
In Washington on Friday, President Barack Obama condemned the latest use of force by Syria against anti-government demonstrators and said the regime's "outrageous" use of violence against the protesters must "end now."
