"Reports on the use of chemical weapons in (the suburbs of) Ghouta are totally false," state news agency SANA said.
It dismissed as "unfounded" the reports from opposition activists carried by Al-Jazeera, Sky and other satellite news channels "which are implicated in the shedding of Syrian blood and support terrorism."
"It`s an attempt to prevent the UN commission of inquiry from carrying out its mission," SANA said.
The Syrian Observatory for Human Rights, meanwhile, said an army operation launched early on Wednesday against rebel forces in the Ghouta suburbs had left at least 100 dead.
A security source in Damascus, contacted by AFP, rejected as "lies" the reports of chemical weapons use in an army drive against rebel strongholds in the suburbs of Damascus.
"There is nothing new happening here because there`s fighting every day.
Operations are under way in all regions to chase armed groups," he said.
Al-Watan newspaper, meanwhile, reported the government had "pledged to cooperate and facilitate the work" of the UN chemical inspectors who launched a mission in the country on Tuesday.(*)
