RNA - "Ahrar al-Sham will never remain committed to this ceasefire," al-Muhajar said.
The Ahrar Al-Sham spokesman said the ceasefire is “unacceptable” because it strengthens the forces loyal to Syrian President Bashar Al-Assad.
"This agreement is only between the US and Russia and it is not related to us and we don't discuss it," he added.
Earlier on Sunday, a political analyst said that there is no guarantee that the long-awaited deal Russian Foreign Minister Sergei Lavrov and US Secretary of State John Kerry have inked to put an end to violence in Syria, would be abided by militant groups backed by the US and some other foreign countries.
Political analyst and journalist Vanessa Beeley said that militants backed by the United States, the European Union, NATO and some Arab states are the "main stumbling blocks" when it comes to implementing the new agreement, Sputnik reported.
The secession of hostilities is expected to enter into force on September 12.
"Historically, again, the reason that the ceasefires have failed is because the terrorists have not respected" them, the journalist, who recently visited Syria. Beeley cited two villages in Idlib, Kafarya and Foua, besieged since March 2015 as an example.
"There has never been a respect of the ceasefire there," she said.
"The shelling of civilian houses has continued through all of the ceasefires and largely been ignored by Western media. And absolutely no humanitarian aid has been allowed into Kafarya and Foua since March 2015 except for a couple of very poorly equipped UN convoys that made it through."
Both Lavrov and Kerry emphasized that the new deal will only work if all stakeholders involved in the Syrian conflict will fulfil their part of the agreement. America's top diplomat said that the anti-Syrian government groups "have indicated they're prepared" to meet the "standards that we have established."
