Evidence Syria "used sarin"

There is evidence that a human rights violation occured when rebels in Syria, have used sarin gas against citizens. The use of this gas has been made illegal by the UN and as a result the case will be brought to the UN as a human rights violation. The author of this article is completely detached from the matter simply listing facts about the event, and quoting others. It causes less of an appeal to pathos making the reader react to the intensity of the situation less. However, their logos is clearly displayed as the reader is fully aware of the fact that their was a violation, and this adds to the already current tension  within this area of the world.
