Britain, France and the United States asked the UN Security Council to hold a vote on Thursday on a resolution demanding an investigation of the suspected chemical attack in Syria, diplomats said.
It remained unclear whether Russia would support the measure, which was slightly revised following negotiations over the past two days. Britain, France and the United States circulated the draft resolution following the strike Tuesday on a rebel-held town in Idlib province that left 86 people dead, including 27 children. Results from post-mortems performed on victims from the town of Khan Sheikhun point to possible exposure to sarin, according to Turkish health officials.
