In an interview for the TV news show 'Vesti on Saturday', Mr. Lavrov said "one can only speak about the ceasefire revival only on the collective basis". Russia and the United States on September 9 agreed to a deal aimed at putting Syria's peace process back on track. It included a nationwide truce, improved humanitarian aid access and the possibility of joint military operations against Islamic State and al Qaeda's Syrian affiliate, formerly known as the Nusra Front. The truce collapsed after a week when an aid convoy was attacked on Monday, killing some 20 people.
