Canadian CW inspector: "Syria chemical weapons cleanup a 'Herculean' task"

CW inspector Scott Cairns was in his hotel room at the time of  the August 21 CW.  Now he and others on the UN team are going back.  He gives his account of that day to CBC.

Nahlah Ayed  writing at CBC:
Syria chemical weapons cleanup a 'Herculean' task, Canadian inspector says.
But Scott Cairns says his UN-sponsored team will give it its 'best try' as it re-enters Syria today.
In the early hours of Aug, 21, Scott Cairns was struggling to fall asleep in his Damascus hotel room when, staring out the window, he saw what appeared to be fresh fighting to the east.
"At that point I didn't know what it was," he said in an interview with CBC News. "It happens on a regular basis …there is incoming and outgoing fire from Damascus, so there are constant thumps and explosions. It was only later, when I heard the reports, that I could put it together."
Cairns, a chemical weapons inspector in Damascus for the UN, later concluded that what he had witnessed from the safety of his hotel room was what is now believed to be the worst chemical weapons attack against civilians in a quarter century.
The timing, Cairns agrees, was odd.
The attack happened while his UN inspections team was on the ground to look into three prior allegations of chemical weapons use in the course of that country's more than two-year-long civil war......
