Human rights activists said at least 15 people have been killed in Syrian city of Daraa, as anti-regime protests showed no sign of abating.

Activists and residents said security forces opened fire on protestors outside the Omari mosque early in the day, after hundreds of people gathered overnight to prevent police from storming it.

A funeral for two of those killed also came under fire, activists said, and shooting continued sporadically during the day.

Today’s killings bring the death toll to 21 in Daraa, a mainly Sunni tribal city near the Jordanian border.

The town has been hit by daily protests for the past week against the regime of President Bashar al-Assad, whose Baath party has ruled Syria for 40 years.

An AFP reporter saw two bodies in the city hospital shortly after gunfire erupted this afternoon around the mosque, where activists have been based for a week.

An 11-year-old girl was killed by a stray bullet when security forces allegedly opened fire on a funeral for two of those killed overnight, an activist said.
