Fears rise that UN could be forced into compromise with Damascus to keep vital corridor open from Turkey to rebel-held Idlib

Aid groups and their backers at the United Nations are pushing to revive an aid corridor into rebel-held Syria after Russia vetoed the renewal of the cross-border lifeline that has been getting food and medicines into Syria for almost a decade.

Moscow has repeatedly attempted to stymie deliveries through the Bab al-Hawa border crossing from Turkey into Idlib, a strip of land controlled by the de facto opposition known as the National Salvation government, which is linked to the Hay’at Tahrir al-Sham militant group. At least nine people were killed in a Russian airstrike on a vegetable market in rural Idlib last month.
