Details are still emerging about Tuesday’s chemical weapons attack in Khan Sheikhoun in northern Syria, but the US, France and Britain have already condemned the Syrian government for gassing its own people. On Wednesday, Nikki Haley, the U.S. Ambassador to the UN, threatened the US may take unilateral action if the Security Council fails to respond. The death toll has risen to at least 72 civilians, including 20 children, according to the Syrian Observatory for Human Rights.
It’s not clear yet which chemical agent was used, but MSF International (a.k.a. Doctors Without Borders in the US) says its medical teams’ reports “strongly suggest that victims of the attack on Khan Sheikhoun were exposed to at least two different chemical agents.” Patients’ symptoms “are consistent with exposure to a neurotoxic agent such as sarin gas or similar compounds,” but victims also “smelled of bleach, suggesting they had been exposed to chlorine” as well. Rescue workers have collected soil samples and sent them to western intelligence officials to determine exactly what was used in the attack, the Guardian reports.
The attack raises several questions, which, tragically, Just Security has considered previously. Here is a selective sample of some of our earlier coverage on these issues, which is as relevant today as it was when it was first written. Watch this space as we provide further analysis, especially the implications for the White House, for global norms at stake, and for the people of Syria.
