The UN's Syria envoy Staffan de Mistura expressed optimism on Wednesday that the stalled peace talks could resume, but stressed it had to happen in "soon" to avoid losing momentum, Daily Mail Online reports.
His comments came a day after talks between world powers on ending the five-year conflict failed to make a clear breakthrough in Vienna.
He also said that negotiators had to "bear in mind" that the month-long Muslim fasting month of Ramadan would start around June 6th "in that part of the world".
