Threatened by rebel advances last year, Assad is now pumped up with confidence after Russian air strikes reversed the tide and enabled his army to recover lost ground from Sunni insurgents as well as the jihadis of Islamic State.
“The terrorists fired rockets carrying mustard gas,” a statement said on state owned Ikhbariyah television station.
The statement by the Riyadh-based High Negotiations Committee came hours after Moscow and Washington said a ceasefire in war-torn Syria was set to begin overnight Friday-Saturday.
He pointed out that countries, like Turkey, must stop sending more terrorists and arms as well as providing logistical support to the terrorists.
If implemented, the deal hammered out during five hours of late night talks in Munich would allow humanitarian aid to reach besieged towns.
But the High Negotiations Committee (HNC), the main opposition umbrella group, remains sceptical, insisting that the regime to allow humanitarian access to besieged towns, stop the bombardment of civilians and release prisoners.
Russia began carrying out air strikes on the positions of Islamic State fighters in September in support of Assad’s army.
IS “didn’t start in Syria, it started in Iraq, and it started before that in Afghanistan,” he said
A Russian lawmaker said on Sunday that Assad had expressed a willingness to hold new parliamentary and presidential elections, but only after Syria is “liberated” from Islamic State group jihadists.

“As long as they follow this propaganda, they will have more refugees,” Assad said in an interview with Russian media.
The Free Syrian Army’s Southern Front is an alliance of rebel groups backed by the US and its allies, including Syria’s southern neighbour Jordan, which offers the group logistical support.
British-based group said at least 110 civilians are killed in 470 plus air strikes in Syria in last 72 hrs.
After three years of fighting in Syria, more than 3.2 million refugees are registered in neighbouring countries.
De Mistura had previously said Aleppo would be a “good candidate” to become a “freeze” zone.
