As was the case in the coastal city of Jabla, the eyewitness said the wounded were being treated in mosques as snipers on rooftops were preventing the injured from being taken to hospital.
Al Jazeera confirms that a campaign has begun to discredit and disable a leading Syrian human rights organisation which has been instrumental in reporting the abuses of Syrian security forces in the armed crackdown on pro-democracy protests.
Wissam Tarif, director of the Insan human rights organization, told Al Jazeera that his website has been left hacked into and more than 2,000 spam messages left on it, effectively crippling the site.
Tarif said his Facebook and Twitter accounts had also been hacked into and hundreds of threatening and abusive messages left.
"The messages said that I am history, that they will kill me and they want to drink my blood," he said.
"They also seem to have a big problem with my mother and other members of my family."
