The so-called moderate armed opposition groups in Syria have reportedly signed a mutual non-aggression pact with the IS terrorists.
The deal, brokered by al-Qaeda-linked group, al-Nusra Front, was signed in a Damascus suburb, the Syrian Observatory for Human Rights reported on Friday.
The agreement stipulates that all sides should respect a truce until the downfall of the government of President Bashar al-Assad.
Over the past few months, the Syrian crisis has entered a new stage as armed conflicts have escalated among different militant groups.
The truce comes as the U.S. introduced a plan to provide more weapons to the so-called moderate opposition groups under the pretext that such militants can fight against the ISIL.
Analysts, however, have already expressed concern over the plan and warned that those militant groups will share the US weapons with the IS.
On September 10, U.S. President Barack Obama authorized airstrikes against the IS positions in Syria for the first time.
The ISIL terrorists control large swathes of Syria’s northern territory. The group sent its members into neighboring Iraq in June and seized large parts of land there as well.
