On 10 September 2016, Russia and U.S. reached a deal on establishing a cease-fire between the Syrian Assad government and a US-supported coalition of so-called 'mainstream Syrian opposition rebel groups' including umbrella group 'High Negotiations Committee' (HNC), effective from 12 September, while jointly agreeing to continue attacks on Jabhat Fateh al-Sham (former al-Nusra Front) and Islamic State of Iraq and the Levant (ISIL).[7] Russian Foreign Minister Sergei Lavrov said that Russia and U.S. had developed five documents to enable coordination of the fight against Jabhat Fateh al-Sham and ISIL and a revival of Syria's failed truce in an enhanced form.[7]
