Vice News: Hours after doctors from Syria offered testimony about a chlorine gas attack in the country’s northwest to the United Nations Security Council on Thursday, reportedly bringing its members to tears, they informed VICE News that their hospital had just received victims of what appeared to be another chemical weapon strike.

At the meeting, the doctors showed council members footage taken by a field hospital in Sarmin, in Idlib Province, on the night of March 16. The video, which was provided to VICE News, depicted frenetic efforts to resuscitate three young children exhibiting symptoms of chemical exposure. The children were inside their basement home along with their parents and grandmother when a crude barrel bomb landed on the building’s air shaft, trapping them inside a cloud of toxic vapor. All members of the family died.
