Snipers on rooftops and forces on the ground shot at funeral-goers in the Damascus suburb of Duoma, a witness said.

"Currently we all are martyrs-to-be for the sake of our rights, of our dignity and for the dignity of the entire nation and the Syrian people," said Riyad Sayf, a former Syrian legislator,  to a crowd of mourners.

Al Jazeera reports:

Eyewitness in Douma on Saturday said that the gunfire erupted during the funeral processions, a day after eight people were killed and at least 25 injured in an attack on protesters.

Snipers took up positions on the top of a Baath Party building near the privately-run Hamdan Hospital, where residents had overnight formed a human shield around the main gate, in order to prevent security forces from arresting those who were injured and being treated inside.

Elsewhere, at least three people were killed in the neighbourhood of Barza at a mass funeral of pro-democracy protesters killed a day earlier.

Two members of parliament, Nasser al-Hariri and Khalil al-Rifaei, resigned on Saturday in response to the government's use of violence.

"I feel sorry for those who were killed in Houran today and yesterday by the bullets of security forces, despite the fact that the president has promised no live ammunition by security forces at all," al-Hariri said.

On Friday, at least 82 people were reportedly killed and many other injured after Syrian security forces clashed with protesters.

As many as 300 people have been killed since the protests erupted more than a month ago. But the exact number of dead is unclear since foreign reporters are not allowed into the country. News agencies must rely on reports from humanitarian organizations and witnesses.

Anti-government protesters demand the resignation of President Bashar al-Assad.
