“ The use of chemical weapons by the Syrian regime is a serious crime of international concern, as a breach of the customary international law prohibition on use of chemical weapons, and amounts to a war crime and a crime against humanity. ”

“ If action in the Security Council is blocked again, no practicable alternative would remain to the use of force to deter and degrade the capacity for the further use of chemical weapons by the Syrian regime. ”

“ Renewed attacks using chemical weapons by the Syrian regime would cause further suffering and loss of civilian lives, and would lead to displacement of the civilian population on a large scale and in hostile conditions. ”
