UN rights probe finds Syrian army responsible for deadly sarin attack

The OPCW confirmed in June that sarin was used, but it did not state who was behind the attack.
The Commission of Inquiry said it collected evidence from dozens of interviews with victims, eyewitnesses, emergency workers, as well as from photos and satellite images.
The rights investigators ruled out an explanation by Syria's ally Russia, which has suggested that chemical weapons could have been released when an airstrike hit an arms depot.
Witnesses have said that there was no such depot, and the commission said such a strike would have destroyed most of the sarin inside the building rather than releasing it widely.
The commission's report linked Russia to the chemical attack.
Russian and Syrian government forces had hit hospitals in the vicinity shortly before and after the incident, "thus preventing victims of chemical attacks from obtaining essential medical treatment."
The UN investigators also said they are "gravely concerned" that the US-led operation to defeat Islamic State extremists in Syria has forced 190,000 people to flee and has killed significant numbers of civilians.
