Sabra said the attack came at a time when a team of UN inspectors arrived in Syria to probe earlier allegations of chemical weapons use.
But the Syrian government strongly denied the attack and described reports as "lies and groundless" blaming international media for covering baseless stories aiming at distracting a visiting team of United Nations chemical weapons experts from their mission.
"Sarin gas used"
Halid Mahmud, a doctor in the region told Anadolu Agency several people were affected by the "sarin gas."
Emphasizing the need for medical supplies, Mahmud said difficulty in breathing, vomitting, contraction in pupils and loss of consciousness were the common symptoms of the wounded brought to hospital.
Mahmud also reiterated the concern over the number of casualties increasing.
Meanwhile, activists said civilians were attacked early in the morning and hence at a more vulnerable time, resulting in more severe consequences.

Attack coincides the visit by UN investigators
Syrian Regime Forces has reportedly staged chemical weapons attack at the suburbs of the Ghouta region near the Syrian capital, Damascus early Wednesday, while a team of UN inspectors arrived in Syria on Sunday to probe earlier allegations of chemical weapons use.
Led by Swedish arms expert Ake Sellstrom, the investigations into the alleged use of chemical weapons will be limited in three areas, including a March attack in the Aleppo suburb of Khan al-Assal.
UN Secretary General Ban Ki-moon had said on Tuesday that, the expert team would conduct its activities in the country for up to 14 days and that could be extended upon mutual consent, as agreed with the Syrian government.
Ban also urged full access for the expert team to the sites where the chemical weapon attacks allegedly happened.
"Let me state again clearly that, if confirmed, the use of chemical weapons by any side under any circumstances must be held accountable and would constitute an international crime," he said.
